If it were 100% the value of the world would be 0% and therefore bitcoin would be 0 as well (because literally everything would be 0) and all life in that moment would cease, as you could not even buy a single laptop to keep bitcoin running. It is not well communicated in the original tweet, but this is similar to the question of, on btc standard, what is the value of bitcoin you hold vs (obviously bitcoin denominated value since there is nothing else) the value of everything else you own (equities, physical property). Just savings vs investment rate.
