Gwern, some anecdotal thoughts from the world of business, where this sort of blind committed self pricing is sometimes called a "Mexican Standoff". Same idea on, say a cap table -- both parties agree that in event of a dispute, they will make sealed binding offers for the whole company; higher offer must pay. I often recommend this to young startup CEOs when they have a team they haven't worked with before, and I've occasionally suggested it to business partners.<p>Although I like the intuitive simplicity and game theoretic aspects of the arrangement, I've never seen it get through a partnership agreement or shareholder agreement round of redlines. Often lawyers feel nervous about it, and they'd prefer to litigate anyway; a space they are comfortable assessing and handicapping (and billing for). Often one party feels less sophisticated than the other, and thinks there might be a trap somewhere in there. Most sense, I think, that this sort of arrangement benefits the wealthier party. I think Harberger taxes suffer from the same sort of problem: the most money wins the asset.<p>You mention, rightly, the absolute trash heap that Brian Herbert has made of Dune. You speculate, wrongly, I think, that this arrangement would have cut him out and protected the IP. Au contraire -- I think Brian has done very well financially from this IP ownership -- sadly, enshittification pays -- and I don't see any reason to think that better stewardship would have resulted in more money to go buy out the IP than Brian's made.<p>Particularly in a world of art and human creative output, I'm negative on forcing IP rights to the wealthiest owners -- I'd prefer a system that leaves it in the hands of people who might have a variety of interests that could dominate, even if that gives us some tragedies in exchange.<p>Anyway, a system of transparent IP with buyout values (or reference values) attached is not, to my mind, uniformly better than what we have -- the reference values will be wrong, they will not capture non-monetary value, and they don't guarantee a ready buyer. It's hard to see what we'd gain; I agree that we wouldn't lose a lot, but there's a lot of social and legal work to implement between here and there.
