However, if Bitcoin is expected to be completely mined by 2140, then for all intents and purposes it has no glass ceiling. Note that our current post Bretton-Woods system has 42 years, and that Bretton-Woods lasted ~40 years before collapsing (leading some to postulate, with the current crisis, that monetary systems blow up every 40 years).

Bitcoin can last 40 years of use without hitting the ceiling.
