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.
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."
As adoption increases, liquidity (which may be what you allude to when you talk about coordination) will be even better.
I'd also note that facilitating liquity can indeed be a complex problem, but there are people specialized in making money out of it and who therefore have an incentive to continually keep the market liquid, read about "market makers".
In theory someone could have coins untraceable to them as long as they never intersect with something on chain that could be traced back to them, but that turns into a game of never spending the tokens when taken to the extreme. Bitcoiners quietly see that as a feature, not a bug, because the goal of the game is to get everyone to buy as much as possible but sell as little as possible. That’s the formula to make the number go up.
Good luck with that.
