That might actually be one of the best points I’ve heard made on this subject. The Feds were able to confiscate gold in a time when prohibition of alcohol required a Constitutional amendment. How much would it really take to declare “we need to protect the integrity of the dollar. Transacting in non-legal tender is like stealing from Americans everywhere”…or any of the similar arguments made for confiscating gold back in the 30s.
How hard would it really be to make transacting in bitcoins illegal? It would be easier and less controversial than sneaking into a foreign sovereign nation and assassinating someone.
And then, yes, it would be difficult to stop people from trading them between themselves…but who the hell is going to continue to use a currency that you can’t transact in with any reputable business?
