Um, that's the least libertarian thing imaginable. Steal from everyone working, pay people who won't.. . And somehow everything is magically fixed!
Except that it's a stupid fucking idea that would destroy our society in months.
Not an ideal of libertarian thinking no... the point is to give people money they can use towards whatever they freely choose versus a thousand different social welfare programs that create a top down approach and impose solutions on people.
There are many people that are incompetent, so just handing out money won't work for everyone. But for people that are simply without enough money to boot strap themselves, giving them money without strings attached would be better than giving them money with all sorts of hassles and oversight which traps them in "the system".
Maybe that means some 3 strikes rule where you get your cash for a while, but if you blow it all and still end up showing up at the soup kitchen looking for free meals then you are cut off and go under supervision and are provided services instead of money because you are incompetent to manage money.
The point is that the libertarian view of social programs is that many are a necessary evil, but they should be reformed as much as possible
