Why?
You're the one who flatly stated they're not entitled to it.
Now, in my opinion, there is room for debate in a society as to what people are entitled to, or not. That economic and social rights, in addition to political rights, are open to debate in a society. I actually think that such a debate would be interesting and productive. Unfortunately, your interest in such a debate seems to end at "well, I believe what Jefferson believed, and he was a Founding Father (TM), so there"
Of course, you are of the position that only the rights you deem to exist, actually exist. And that they exist because, as you so eloquently put it, they do.
Now, in some countries, the majority of citizens believe that they
are entitled to universal health care. The view of the American people on that subject would seem to be mixed. Again, of course, in your view, they are
not (full stop) entitled to it. Because you say so. And any attempt to tease out your reasoning beyond that results in hilarity and evasion.
