You are suggesting people be able to insert an encryption module into other services? Or that everyone has to constantly manage a non-default set of tools, and deal with all the interoperability issues of all the mish-mashes of choices others make? Or, ...? Personally, I cannot see a safe online world that doesn't have hard privacy. Why not give people easy ways to report "very bad behavior" online, to authorities that build up a reputation of responding responsibly. Including bounties for the most egregious stuff. Then every recipient of anything rotten becomes a honeypot for the criminals. Breaking everyone's privacy is going to attract every nefarious and security conscious actor in the world to the buffet. Every state actor, "good" or "bad" is going to want to have access to everything that can theoretically be accessed. Worst possible kind of honeypot.
