There is nothing stopping you from having more than one identity. If you don't mind too much if malware has your PGP details, then all good. If you would like a more way to securely store these details for other sorts of communication, perhaps a different machine, a live-CD or hardware token[1][2] can be justified.
I think it is also worth remembering that even the most liberal western democracies have laws that one way or another prevent people from keeping secrets from the law. If everyone has it, and uses it, and it cannot be back-doored, it will be banned rather quickly IMHO. And the people who don't care about privacy -- i.e. most everyone -- won't care about crypto being banned either after the right wing press is done with them. (Restated: we shouldn't force people to close their curtains any more than we force them to open them).

I'm rambling, sorry.
Both of these might also work with your phone via NFC. [1] https://www.fidesmo.com/ [2] https://www.yubico.com/products/yubikey-hardware/yubikey-neo...
