Julia, I will fight to the death against the so-called "right to health care". I am willing to kill and be killed over this issue. Are you?
It is a matter of principle. Economic rights - such as right to health care, food, housing, job etc. are totally, absolutely, completely incompatible with freedom. Those "rights" imply that somebody must provide them. And who is that somebody?! You cannot have any rights that impose any obligations on anybody else. Just hypothetically speaking, suppose you have a right to health care but nobody wants to be a doctor. Do you realize that the only way for the government to provide such a right to you then is to force somebody to become a doctor against his will, and that means enslaving that individual.
That's the philosophical difference between economic "rights" and real rights. Real rights are purely negative in terms of what the government has to do - e.g. it merely has to refrain from persecuting you for speaking your mind (however your free speech right does not impose any obligation whatsoever on anybody else).
