>>if an entrepreneur can invent their own money and subsume the one issued by a government then you don't have a government. I for one prefer having a government.
Nonsense. We've had non-political money before. During the free banking era we had thousands of bank-issued currencies that competed in an open market, and the state was alive and well.
The state exists as long as it has a monopoly on force within its jurisdiction. It doesn't need to monopolize the control of money and imprison anyone who has wrong-think about what they consider to be money.
I understand that a lot of people here don't like cryptocurrency and the get-rich mentality around it, but understand that when you call for laws to prohibit various uses of it, you're calling for people to see the inside of a prison cell because they have different ideas about what money is than you.
