optimal solutions might involve people believing something unfounded, and rationality will never converge to this solution
The fact that we are here discussing this is proof by demonstration that rationality can notice the problem.
The (supposed) fact that we cannot immediately implement the obvious solution is a flaw in the structure of the human mind, which is a problem rationality can solve, with sufficient effort, should we decide to do so.
The assertion that there is no other solution available using our current minds does not (AFAICT) follow, and relies on facts not currently in evidence.
