IMHO the problem crypto leftists have had is that our implementation choices generally ignore the "decentralized" requirement to avoid difficult economics problems. We try things like having nonprofits checking IDs, or creating yet another money supply so we can pay the devs from it, or recreating treasury bonds because it looks greener.
What we need isn't "open source money, but generous". We need to build a new economy outside the old one, and what we're selling won't shoot to the moon overnight. While we can contribute useful tools, we aren't the architects of that future and can't be in charge even for now.
