The main lesson should be that we simply can't have every benefit in any tool. It isnt possible right now. That's why I'm less inclined to alienate people simply because they use different tools than me. And it isnt like a Bitcoiner can't use Monero ever. Nor does one need to give up custody of their entire stack to use ecash or whatever. People draw strict lines and I don't see the benefit of it. Ideally, we will end up with many tools that are easy to switch between for different purposes.
