I dunno. I kinda look forward to the news stories about the Economic Collapse of 2035 being due to the market finally realizing that too many supposedly AAA Date-Backed Securities were actually Non-Investment Grade Junk Dates, and the subsequent revaluation of the Date Market caused the entire banking system to become insolvent because all the dates they were holding on their books as marked to maturity are in fact never going to be anything but immature, and consequently must be marked down to their actual market value of Zero.
I mean, it's a pretty realistic economic threat. Who doesn't have a story of something they anticipated being a AAA Rated Date turning out to have junk date status? Definitely a lot of mismatched incentives all the way around.
Sorry but I have quite a viscerally bad reaction to such a proposal. Sure it could work in some sense of finding value price pairs or whatever where people's preferences aren't clear.
But it also seems extremely dystopian and horrifying, particularly applied to the dating market. It would be similar with finding friends. People do this naturally and normally on their own for free no problem if you put them in a big room together. It neeeds no incentive
