As I've said elsewhere, what bothers me about the perspective of the OP is they way it uses government dependency as an excuse to expand government power. Here it only impacts poor people (freeloaders), so conservatives don't see it as a problem. It's when it's applied to other government services that the idea will come home to roost.
Anomalism has been quite candid that the same principles apply to health care. By the reasoning of the OP, anyone who benefits from government is living on someone else's tax dollars and must forfeit their autonomy. "You didn't build that"
This is exactly why I've always opposed welfare. It's an invitation for statists to use government "largess" as a means of control. It's already happening. And with more and more people agreeing with the OP, it's going to get worse.
