We all KNOW Bitcoin is superior to any Fiat or human devised economic scheme. As you point out it's also impossible to confiscate, if you take the time to learn to secure it in this way. There is no need to "Believe", because it is as true as math - absolutely provable. Any Bitcoiner who thinks they are socialist; have some real soul searching and thinking to do.
To "Believe" in Socialism means you believe in MAN. Man, particularly groups of men (and women), are easily manipulated through incentives (and blackmail) against the populace. You can only base belief in Socialism if your emotions are based on the hope for an impossible Utopia. And you suspend all knowledge that men are corruptible, greedy, lazy, and/or thirst for influence and power.
Tax is theft. You are taking that which is not yours to do possibly against the will of the owner an earner. There is no deep reasoning or logic puzzle as to why criminals are criminals; they simply choose what seems to them as the easy path, consistently - at risk of consequence. Any crime problem exists only because the punishment isn't terrifying enough.
I'll spend what ever treasure, and bitcoin, I can achieve in my life working for human freedom. I'll even fund and purchase tools to undermine, destroy, and even kill a non-freedom agenda. :^) Have a happy weekend!
