A right to those products and services implies the right to compel others to provide them. But that would make slaves of those so compelled. In today's welfare state, doctors, nurses, and manufacturers of medical instruments and pharmaceuticals are not typically forced to provide their services at gunpoint. So this critique may not seem germane. But although providers are not compelled, the taxpayers are.
Taxation is somewhat less egregious than conscription, but it is still compulsion.
Taking people's earnings is tantamount to taking their time and labor. Since the compulsion of taxation is spread across large numbers of people, it is less noticeable than the conscription of medical personnel. But it doesn't fundamentally change what's going on. Someone is being forced to provide something to someone else without there being a freely accepted contractual obligation to provide it. The fact that those who are taxed at times also are beneficiaries of coercively financed services does not alter the picture.
