I'm certainly curious about this. One of my first posts on Steemit was about how Steem might power a basic income. I also highlighted some of Dan's posts here: Outside the Tribal Meme Space: UBI for Non-Socialists, and I find his latest thoughts on this quite fascinating: Universal Resource Inheritance.

KYC type stuff is certainly a challenge. I've put some thoughts into that here Privacy, Identity, and Human Flourishing and again, Dan has some interesting ideas as well: Does Freedom Require Radical Transparency or Radical Privacy?

I don't know what the answer is, but I do think at some point in the future we'll need it.
