My insistence on sales tax-based UBI is twofold: UBI without sales taxes only creates inflationary economics, and sales taxes without universal support would be regressive.
Yanis' scheme is noble, but still dependent on the idea that groups of people can swear moral allegiance to their isolated piles of money.
I would rather tie the effects to the two things people need: resources and informed choice. Anything done away from the purchase point becomes external from the individuals' real necessary trades.
Does that make sense? I'm just throwing darts at stuff anyway and seeing if something pops.
