In the most general sense, it is desirable. Of course. That would be really nice, like ending hunger or not squishing kittens.

However, the costs will outweigh the benefits because your biggest problem (ID aside, that could probably be done with DNA and cryptology, public/private key, PGP, et cetera) is how to hand out free money such that the net result is not exactly the same as the market result available prior to peeps gettin' their free dough.

There's no point to all this not inconsiderable effort if the net result is zero. That is far more important. How will you address that issue?
