Who are these 'I want free stuff' people? I keep hearing them mentioned as some sort of strawman, but no one can really find me any large groups of these people demanding free stuff. Most people realize taxes pay for welfare benefits.
It also appeals to people who want to eliminate 20 government and various state agencies for a single entity. We already have many convoluted forms of welfare, why not simplify it?
The whole point of a government is to benefit the welfare of its civilians.
