I think it's possible to build services that enable users to evade the dragnet, whether criminal or potentially governmental. If either of those communities is targeting you in particular, it's much harder. How many people use universal 2FA? How many do it from their phones, which are potentially vulnerable? If not using 2FA, how many have typed passwords in front of security cameras? And if you are targeted, as someone else pointed out, rubber hose decryption is always possible. The thing that is having people feel like a Christian Scientist with appendicitis (credits to Tom Lehrer) is the concern about the scope of information capture and the security of the systems and people that have access to that information, and I think one can build sound services to help address that level of privacy.
