I agree but I think just having your own VM in the cloud solves this. If each user has their own IP then you can basically get E2E encryption between users with SSL so you don't need to worry about encryption as a developer or user. I really don't like the idea of assuming people have access and relying on bulletproof encryption on a completely decentralized system. I would much rather trust a cloud provider that I'm paying for.
