"Hmmm... do you think it should come in more denominations? It'd make it harder to keep the values matching right and most of the added liquidity is supposed to come from certificates, but those will be in all kinds of weird dimensions... is there a way to make the certificates divisible, besides just filling out a bunch for fractions of the surplus..."

"I think you'd have to fill out ones for fractions but that's not that much inconvenience really. Maybe it'll inspire more people to learn to write. It might be useful to have a very large denomination so anyone who does something big doesn't have to carry around a whole bag of them."

"Ooh, there could be stamps - if you stamp a piece of paper does that reliably carry the you-can-be-sure-it's-not-lying property - you don't generally have to worry about people stealing, right? So carrying them around would mostly be for intercourt trade?"

"Stamping something is the same as writing it. Theft is very rare, you'd mostly carry it when you wanted to redeem it for something."

"What kind of big and little denominations do you think would wind up being most convenient? The little one should probably be like - I remember reading something about small debts dissolving over time, so something small enough that anything smaller will do that unproblematically, and then the big denomination should be big enough that trying to haul that many little ones to another court would be an impediment to trade, like... certainly at least a thousand times the value of the little one, maybe more."

"A thousand would be pretty inconvenient to carry, I think, and most debts are less than a thousand times the value of a debt just large enough it won't go away. You could do five hundred but if a thousand is desirable mathematically that seems fine too."

"A thousand isn't special, I just think if the certificates are yea big - about the size of a bill from the era of paper money among humans - then one person can carry that many if they're packed up neatly. Five hundred's fine. People might start trading for bigger things when they can do it with money, though, I'm not sure current typical debt sizes are a good guide."

"I hope they do!! If a thousand isn't that hard to carry then we can do a thousand, I haven't seen how they'll pack."

Cam checks his computer for a second, squinting at the blinky screen. "Yeah, you can pack a thousand dollar-size bills in a container yea big," he says, gesturing a briefcase-size object.

"Huh. Then that's great."

"Packing efficiency probably goes down if people are stamping random scrap paper instead of using standard rectangles but I don't think that much, you might need two briefcases."

"Still so much easier than trade used to be!!"

Wag wag wag!

He beams at him. They reach the edge of his court's territory. "People will be along to ask our business shortly, I expect."

"We just wait here?"

"We can keep walking if we want, but we should be careful not to break things."

Cam looks for a good place to sit, since probably it will be complicated in some way if he makes a chair.

There are rocks and roots of about the appropriate size.

Plop. Cam makes himself a churro and starts munching it.

Faeries are along in a little bit. Econ Faery explains their mission, and they are offered an escort to the court.

Assuming Econ Faery does not indicate that anything odd is up about this Cam will follow along!

He seems to think this is as-expected. "Think of any other survey questions for them?"

"Do my operating hours sound inconvenient enough?" suggests Cam.

"Sure. I think we'd need five or six questions, in a typically sized court, for that to pay for our demonstration all by itself."

"I can try to think of more but right now I'm stuck on 'would it be nice if the coins came in different colors' and that can't possibly be a very valuable question. Can it?"
