I assume you meant "doomed not to work"? They "work" in the same way prisoners dilemma works, and the expiration date is until the moment one of the prisoners do not cooperate. This is what you describe as "problem" - and the another prisoners dilemma is created (another political system), which solves previous "problem" - makes it that "prisoners" have to work in different way, and the expiration date is until they figure out how to game the system. My idea is that there is no proof yet that it is impossible to create such system that to an arbitrary small probability you could be sure you are not being gamed, and that is what i referred to "pure system", or may be called zero-trust system as well. It may be that it is unknowable whether such system could exist or not, in that case the search for it might be eternal.
