While I don't take argument with your premise, I would like to highlight one reason why UBI will fail. Inflation.
Bringing up the bottom raises the spending and in turn supply/demand comes into play.
While you very well could actually be right in that crypto could provide the infrastructure needed, the rest of the markets would have to be way ahead already.
Now for nations that have a hard time establishing an economy, crypto absolutely provides all the necessary means to building and maintaining a level of growth.
Resteemed!
