I have close acquaintances who will take that $50, spend it on drugs, and then starve to death. If you want them to stay alive, you have to give them non-money.
If everyone spent money like a rational, 100 IQ individual with a moderate amount of schooling on basic financial strategies, it'd be a lot easier to manage a population. Unfortunately, less than half of the population is 100 IQ, and in some areas less than 5% of the population understands a single high school course worth of financial management.
And then of course you have fundamentally irrational actors as well, like drug addicts. IQ and education don't help there, addictions are monsters that swallow people of all socio-economic varieties.
So you have to either let those people squalor, or find another solution.
