Ego:Edit: My whole point is that we really need an attitude change more than anything; as long as there are enough individuals who think they have the right to steal money to fund art museums, we are going to have people stealing money to fund art museums.
There is a difference between believing something and acting it out. That difference is the cost. Under democratic law-making the cost of imposing one's will on a minority is externalized, therefore promoting the belief. If this externality does not exist, certainly one may feel they deserve free art museums, but one does not have the means to execute it without fighting, which then makes it not free at all.
Whatever one may think his rights are, his real rights are what others will defend him for. That is what the law defines, and that is why the law is our objective.
