It does not need to be all or nothing though. It simply needs to be true for a large enough number of people, to create an extremely valuable market.
We are over 8 billion on earth, even if as little as 1% of the population rely on it directly or indirectly due to some form of oppression real or perceived due to political opinions, a long investment thesis on bitcoin can make sense.
I am not a bitcoin holder once this is said. Arrived at the party too late IMHO, and i have better investment options for now from a risk-adjusted perspective.
However if i had more cash to invest than i know what to do with, i'd definitely take a long position on bitcoin.
>even if as little as 1% of the population
1% of 8 billion is 80 million. Coordinating that many people onto a particular platform or alternative is a gargantuan task. It's not "little."
