Cryptocurrency has essentially reminded us that "a censorship-resistant, permissionless hard money" is a far greater enabler of "the bad guys who would take away our freedom" than it is an enabler of "the little guy trying to secure his own freedom".
This is the bitter lesson every anarchist learns — by tearing down the establishment, you're not creating "actual anarchic freedom" — you're creating a utopia for pimps and thieves. It provides a huge raft of new freedoms for organized crime, being a massive catalyst for money laundering and the like. It provides surprisingly few freedoms for the little guy, since nothing's protecting you from theft by the same mobsters. Seriously — if your BTC wallet gets stolen/exchange gets hacked, you're basically fucked. And it's at its worst in exactly those countries we'd naively think would be helped by some underground currency, because there's nothing to stop the mob from robbing the little guy in a place like Russia. We moved away from gold for the exact same reason.
This is to say nothing of all the scams, ponzi schemes, environmental damage, etc, etc, which are several additional shitshows on top of what I just described.

Anarchy is always a more powerful tool for the bad guys than it is for the good guys. It's an iron law of history. The bad guys will always capitalize on the inherent power-differential of organized groups versus a disorganized group of individuals. As soon as the good guys try to fight back by banding together —— then they've violated the principles of anarchy. At that point they've simply created a new government, with censorship and granting of permissions.
Le Roi Est Mort, Vive Le Roi.
