If there’s anarchists on Hexbear and none of them speak against AES, it’s because they know not to mention it.
I guess I could see some anarchists support vague nonsense that sounds similar to an ML. Like having even less sympathy for an openly capitalist regime than ones that are or purport to be socialist. But they’re obviously not anarchists if they genuinely support some states.
I’m aware not all coins are proof-of-work mined using coal generators. Proof of stake isn’t punk either.
In all honesty there’s nothing to make better, I believe the central issue with crypto is that it doesn’t solve any real problem.
