"Democracy is two wolves and a sheep voting on what to have for dinner. Liberty is a well-armed sheep contesting the outcome".
I see no moral hazard in coercing people
and that's the problem. Coercion is inherently immoral as it denies agency, which is the very essence of humanity. Agency / self-control is the fundamental difference between being a human being, and being a piece of property.
There's also the argument that the money you own isn't truly yours. It's the product of a large amount of investment on behalf of your parents (which varies for everybody) and the government in terms of education (of you and everyone else to create an economy where you're able to perform your current job) and infrastructure, with the end result of you being able to perform your job. So its taxation is not theft because you do owe that money back to the rest of society. I think preventing hunger/homelessness is in general a good way to spend that money
Living in groups--and people are very much social creatures--means there are rules you follow that you didn't necessarily decide on, or ultimately you get kicked out of the group and probably don't continue your genetic line.
Left unqualified, that's kind of a silly claim to make--it sounds good to some but doesn't really get us anywhere.
The question is how much the rest of us are involuntarily having to provide for them, and more relevantly, whether or not society is even really being improved if the result is an increasing number of people so unable / unwilling to contribute to society that they can't even be bothered to show up for an interview.
It is very easy to spend other people's money supporting people perceived as downtrodden. It just might not be the solution proponents think it is.
