They don’t. As I already explained, these examples are bad because the outcomes are not all bad, in addition to not reflecting the same causal patterns or being driven by adverse selection. The only consistent thing here is a Marxian paranoia that everyone else is naive and being ripped off in trades. Which is a common cognitive bias in denying gains to trade. The subway car is simply an equilibrium. You cannot tell if ‘you’ are better off or worse off in any car, so it is not the case that ‘the deal is bad’ The room and food examples actually imply the best outcome happened, as the room and food went to those who valued it more and so ate it sooner (it’s not about correlation of preferences, it’s about intensity); the deal was good there. And the Laffy Taffy example explicitly doesn’t involve anything like that but is pure chance (so it can’t involve “other people’s maps” or ‘adverse selection’).
I think you missed the point of the Laffy Taffy example. He got the flavor he didn’t like because he’d been systematically eating the ones he did like while leaving the flavor he didn’t like in the bowl. (Or his friend wasn’t actually picking at random.)
