The purpose of bitcoin is to be used. Once it has seen enough adoption, you don't turn it into cash. It is cash.
Also I do local bitcoin transactions just fine thank you very much.

Therein lies the rub and the crux of my point. A government WONT LET IT see enough adoption that you can subvert the sovereign monetary system.
I think you underestimate how big of a deal it would be to move 100% of commerce off of the USD. Nations go to war for less.
Go try and turn your Bitcoin into cash and then tell me how true this statement is.
