I don't like reductive economics logic over what is a humane response, but I do like that it may not only be nicer, but actually financially sensible.
(Also note that if that's your general policy then you effectively allow anyone to blackmail you to get whatever they want, just by making it slightly more expensive to not give them what they want)
Maybe. Reductive reasoning is usually a good idea.

So what? If and when you manage to fix the US health system for the working poor then it might become reasonable to provide free healthcare to the disruptive homeless, sure. But until then it isn't.
