Is United States anonymous? Or can people be anonymous in United States?
Ofcourse we all know the name of the Country is United States, so the name isn't hidden. Besides anonymity is typically used for human not a Nation. Same as Bitcoin(the Network and currency)... the name is Bitcoin, but Users can be Anonymous like Satoshi said.
Well you went pretty deep into the semantics of OP's wording, but I guess he didn't even think as far as you now took it. Honestly speaking staying as anonymous as Satoshi managed to do is almost impossible for the average user. Or let me reiterate - it is impossible for the average user. Satoshi put enormous effort into leaving no trails and a normal guy with average knowledge about OPsec and what not wouldn't be able to leave no trails, especially not if he or she is a frequent Bitcoin user.
