A right is something that everyone has.  The fact that A may deprive B or his or her rights in no way means that B is not entitled to his or her rights.  The right to life is denied when people are denied needed health care.  That does't mean the right to life does not exist.  Nor does the fact that A may defraud the health care system provide any justification whatever for saying we should get rid of the system.   Get rid of the fraud is the obvious answer.  You know, there are policemen who defraud the system too - that doesn't mean we should abolish policing.  When the ability to pay determines whether or not one receives health care, one is simply selling life to the highest bidder.  As Pope Francis notes in Evangelii Gaudium, ours is an 'exclusionary' economy that 'kills' and turning health care into a mere commodity for sale is a symptom of the idolatry of wealth that puts profit before life.  And that's completely opposed to everything Jesus and his followers stand for.
