Bicameral sends a couple of the Marlatias over for this conversation, while sending other breakout groups to discuss similarities and differences between Chaos and Carolingia's "male homosocial environments", to more thoroughly convey the expectations that would hold if they did choose to designate some of the cave as Chaos, and to explain the multiple personalities thing in further depth to anyone who wants to know.
"So the goal here is that the person who invested in building or designing something is financially compensated for the labor, out of the surplus value that their work produced? We also have systems for that, though we mainly do it by paying out bounties – or funding someone in advance to work on a project, if they have a proven track record. Most people have diminishing returns on wealth and if inventors and architects and such were collecting a percentage of the gains forever, it would end up - kind of disproportionate? Though sometimes the bounties are very big, or paid out multiple years in a row if an invention is gradually catching on and seeing more use. Anyway, ordinary people - and organizations, too - pay into various funds that are used to pay out as bounties, which ones in what proportion depends some on their own work and what tools they use there, and then there are contests or judging panels that allocate those funds. Attribution for work done is separate."
Also, importantly, none of this really applies in the Underworld, which is transpires seems to run mostly on a...gift economy? Despite easily soaking up 25% of Bicameral's total GDP, in a completely decentralized way. Most industrial production is done on the Surface, but most art and fiction happen in the Underworld, meaning that authors' compensation is also done in a completely decentralized way. Though it sounds like there's enough surplus sloshing around, brought in by people whose main career is on the Surface but who value their Chaos time, that the Underworld can support something like 0.5% of the population living full-time in the Underworld as musicians or visual artists or writers or actors, etc.
If other worlds want 'intellectual property' to apply to creative works, Bicameral is...genuinely not sure how they would implement that, short of making it illegal to consume other worlds' art or media in the Underworld at all but that would make people sad? They could maybe open some new bounty funds, and allocate payouts based on - some sort of survey data about the popularity of various media, to estimate the value provided? Though it'd be biased a little by the fact that a solid fraction of the population either has strong principled objections to recounting any of their Underworld activities on government surveys, or else has a sufficiently sharp delineation between personalities that they literally won't remember while operating in Lawful areas.
