It is interesting that people care about what will happen to bitcoin after the year 2140

MOST people don't. MOST people are short term.
I have a belief in reincarnation. Not a very strong belief but there is some scientific evidence. I don't really care about the fate of Bitcoins in 2140. I do care if there is a civilization that even remembers the meaning of Liberty in 2140 but there isn't much I can do about it.
