I see this claim made a lot, and I don't understand it. When the canadian trucker protest (please don't make this discussion about that, I am not saying it was good or bad, I am just using it as an example) switched to crypto after the gov froze their bank accounts, the gov also froze those crypto wallets. That seems like the opposite of powerless.
I think it's really naive to think that the gov won't just be able to bully any type of new system into submission, like they always do. If there are people running the system, then those people can be coerced.
So for most people this can just be shortened to "Cryptocurrency can't help you".
These people didn't do anything wrong either:

It would not be enough for the young to care about anonymization. They would need to care about it far in excess of their desire to interact with common platforms, celebrities, pop culture and their peers. It is an unreasonably high demand for kids.
