For want of better artistic media in the dismal 'public housing' space-station, Isaac is drawing on the metal floor of his room with food ash. He'll probably get in trouble for it, but he doesn't care at this point. The picture shows a wizard summoning a demon with a magic circle. The writing around the sides is in Greek, because he wanted something that looked fancy but he didn't just want to do random nonsense.
"I haven't been keeping up with media for more than a decade, and I can't afford a tourist trip. I remember Daisy Wilson's books being good, but I don't know if that's just nostalgia. What are you offering in the way of stuff? I could definitely use some more stuff."
(The apartment is undecorated and sparsely furnished, and what furniture and possessions are in it all appear cheap and low-quality.)
"Wow. Could I have, uh, a luxury space station like the Paulos all to myself? A luxury spaceship to get me there? A hundred billion dollars? A robot army to take my home back from Zijin? A knighthood? An art degree from a fancy school and a job where I get payed to do art? A destructive brain scanning device and a computer server capable of running an upload? Something nice to eat?"
"Counterfeiting money is unwise for reasons unrelated to its physical representation. A knighthood is not stuff and neither is a degree. I'd need a good place to put the space station and the spaceship, and also, knowing how to fly a spaceship isn't stuff. If you folks have invented army-type robots and brain scanners for uploads I could copy them but might want to think about that for a while and learn some background context first. What do you like to eat?"
"I don't know enough about astronomy to tell you where a good place would be to put a space station, and I suppose a building permit probably isn't stuff either. It probably doesn't matter what you make me, if you can't make social constructs or robot armies they'll just come up with an excuse to take it off me. Maybe a really fast spaceship and a station out in the Oort cloud it won't be worth anyone's while to come after me. Could I have honey glazed tomatoes and steamed asparagus? Maybe some landscape paintings and adhesive painting hooks too. And some Daisy Wilson novels to reread."
"Hard copy is good. I don't have a particular expectation for who will take stuff you give me, just, powerful, rich, important people. My situation is that Zijin decided they wanted my land and the Council decided they wanted to let them so now I'm stuck here in public housing that's basically a prison, applying for shitty jobs that don't want me so I can get welfare that barely covers the cost of the terrible food that's the only stuff you can buy here."
"Space is cheaper 'cause it doesn't get in the way of mining, is the idea. Plus it's cheaper to keep just the atmosphere of a space station breathable than the atmosphere of the whole Earth. The Council are the people who are in charge of everything in the inner solar system. Zijin is one of a bunch of mining companies they're dividing the Earth between."
"If the humans you're familiar with have afterlives, that would explain why they don't have uploading. The main thing people want uploading for is so they can outlive their bodies, so we probably wouldn't have bothered to invent it if we just became immortal demons when we died anyway. Where else do demons come from, aside from being dead humans?"
"So it's not the same humans summoning you as have you as an afterlife? I suppose the lack of uploading could just be a matter of just being less technologically advanced in general, I think you mentioned not having robot armies either, and I'd expect people to make those whatever the afterlife situation."
Companies advertising help with the process, mostly. Also a magazine article offering tips on the process, a magazine article talking about why it's a good idea, construction companies, 'Orbital distribution' companies which appear to offer specifically the service he's looking for, a computer game and a bank that mentions it as something their loans are useful for.
Orbital real-estate sale and registration for businesses (or occasionally for private individuals), sometimes advertising specialisation in particular ranges of distance from the sun, in specific ranges of space-station mass, or close to and on a similar orbit to some other space station. Clearly targeted at people wanting to build space stations. Prices are presented which vary by mass and distance to the sun (heavier is always more expensive, but cost increases less than linearly with weight). Most companies seem to sell real-estate specifically in the Inner Solar System. Purchases can be made online.
"I don't know how many questions people are likely to ask where. Paulos and the Foundation Ring have more money than anywhere else, and Riordan is the biggest commercial centre. Cui University has a reputation as paying a lot for anything of academic interest, but I expect they'll ask questions about it. If you want to sell your world's art to people who want to pass it off as theirs that will probably go for a lot in Riordan or Diallo. If you want to sell minerals a lack of questions is hardly the biggest concession people in Paulos or Foundation have given in exchange for them, and even if they ask too many questions their suppliers in Riordan might not. People in Riordan and Diallo pay a lot for uploading, so if you can undercut Kensington by even a bit they'll probably pay a lot for that."
Isaac will lead him out of the room, through an extremely long (probably somewhere around a mile) corridor, around a corner, along a similarly long corridor which doesn't have doors but has other corridors coming off the side and more people walking through it, to a set of lifts across the corridor from a grocery store. At the lifts (which have hundreds of buttons) he takes them to a floor labelled "E" (one of two floors designated with letters rather than numbers, the other being "S"), where they open onto a train station. After numerous stops, he will lead Cam out of the train and into a room with a number of doors on the opposite wall.
The room contains a large number of people in what appears to be some sort of futuristic blue armour and armed with rifle-like weapons, many of them escorting people in less uniform, shabbier clothing, similar in style to Isaac's but less well-made and more ornately decorated, into the train station. In some cases, the civilian-looking people are resisting and being taken into the station by force.
"They're docking ports, not airlocks, opening them without a spaceship on the other side would kill everyone in the room, so the police won't let us do it and there's safeguards on the doors to make it physically impossible. Suicide by vacuum isn't illegal, but entering a spaceship without the owner's permission is and the police aren't going to assume we have permission to be on any of the spaceships."
