This is better than nothing, but the big advantage of the UBI is that there is no bureaucracy deciding who gets it and doesn't get it. If there are any conditions on the income, then there's a constant danger that the program will become another tool of control.
Feb 1: receive monthly UBI payment Feb 2: spend all of it on strippers/drugs/alcohol/twinkies/etc. Feb 3: I'm hungry.
Unless you are prepared to let the idiots starve to death, UBI will never work.
