This advice tends to be akin to the advise to disable JavaScript. Basically at this point why are you even on the Internet? Also, as you mentioned Flash, Java, and especially SVG. The only real mitigation here is full drive encryption with a long passphrase which you'll never give up. Of course in the eyes of the courts and public that's a serious double-edged sword because you are assumed guilty at that point.

This is a good argument for Full disk encryption with a vpn and dns leak protection. You're right about people using encryption too. They have a whole playbook dedicated to targeting encryption(physical access is page one).
