I hear this all of the time and I want you to explain the sustainability of a system that is constantly using force to TRY to steal something and never getting it. At what point does the cost outweigh the effort.
Violence is expensive and while in the short term people will suffer while fiat circles the drain. On a Bitcoin standard, you have to have cooperative means of accumulating bitcoin or you cease to exist.
Sure, preach to a den of theives and vipers to change their ways but a scorpion will sting you on the back as you carry them across the river. Just know whether you help their souls or not, Bitcoin does ALLOW them to steal it and thus drains their funds as they fight against incentives.
