Because those are money paid for (saved up) by the same people while they were young and employed... Where would this basic income for everyone magically come from? It maybe would be possible if the rich (millionaires and especially billionaires) and corporations would pay for it with higher taxes, but since they run the world, I'm guessing that's not gonna happen. Seriously, the current welfare systems are quite ok (pay only those who don't have enough and/or don't have a job), just streamline it and tax the rich a bit more for more money to go into it. Europe seems to do it best so far. But of course that's socialism, etc. (and somehow basic income isn't)...
