I basically agree -- even if all guns were banned, I'd probably confine myself to voting, organizing, pushing for legal changes, etc. If it ultimately failed, I'd move somewhere with more liberal gun laws, like Canada.

If cryptography and free speech were banned, and the legal routes were exhausted, I'd use cryptography and guns or other energetic chemical reactions to resist what were clearly "all enemies, foreign and domestic".

Guns and crypto: better together.
