The primary use case of Bitcoin is to evade governments control over capital. Sometimes that’s good (governments disgorging kidnappers of their ransom). Sometimes that’s bad (Nazis seizing wealth of targeted groups). Sometimes it depends on your perspective (governments preventing the trade in illicit drugs).

Overall how you feel about this in aggregate will depend on how comfortable you are with government power. Let’s even ignore the fact that Bitcoin today is being used to circumvent unquestionably oppressive governments (Venezuela, China, Iran). Even as a hardened libertarian, I’ll freely admit that Americans and Europeans live under a generally fair and just government. Bitcoin is still worth it as a fail safe against future totalitarianism.

It’s the same reason I support the Second Amendment. Having a bunch of people run around with guns probably doesn’t help much today, and may even have ongoing social costs. But it would make things a hell of a lot harder for any would be tyrants. Not that it’d be impossible, but small frictions can have big impacts on the course of history. That’s a civilizational insurance policy worth paying.
