Hey I've no idea of anything, and don't have a dog in this fight either, but reading everything here I think decentralization is actually the answer. Yes, you'd not get that global reach, and your network of contacts would be severely limited (presumably to those you know). But a decentralised system could do E2E and P2P and run from home. Running that beside traditional, clear-text and consequently spam-proof email strikes me as a sensible balance. One (open, centralized) system for global comms. Another (closed, decentralized) for secure comms. Maybe even more than one "another", if contexts require different audiences.
