Moreover, "limited government" in the context of American founding principles refers to the allocation of responsibilities between states and the federal government, not the overall scope of government.
There is, in fact, a principled originalist argument for universal healthcare. First, it has always been assumed that the states have the power to provide for the welfare of their citizens, as well as to police their behavior and morals. The states are, in that regard, decidedly not "limited governments" of "enumerated powers." State-level universal healthcare is contrary to no founding principle.
Second, the Commerce Clause was incorporated into the Constitution to allow the federal government to solve what we today would recognize as economic collective action or free-rider problems. At the time it was aimed to address the collective action problem of free trade. It's good for the United States as a whole, but individual states have a short-term incentive to erect trade barriers. The purpose of the Commerce Clause was to allow the federal government to counter-act those short term incentives. Precisely the same problem exists with state-level universal healthcare. Even if most people in a state want it, they can't enact it because it's too easy for people from neighboring states to free-ride on those services. The Commerce Clause is thus properly invoked for resolving that problem at the federal level.
How so? If you are a resident, you get "free" care. If not, you get a bill. Is this not how Canada works WRT Americans who need to use the Canadian health system?
The Constitution imposes an open market on commerce and movement within the United States. The Commerce Clause exists to give the federal government the power to address the economic issues that arise as a consequence of that.
I don't see Americans adverse to Medicare, which is essentially single-payer for anyone over 65. Why does being under 65 mean you should die in the street without healthcare?
Single payer is cheaper/more efficient than our current system. We just need to find the political will to implement it, and cut the legs out from anyone attempting to stymie that change who is currently profiting from the status quo.

Personally I think it's the combination of anti-socialism brainwashing and the "I got mine so screw you" attitude too many people have.
Associating a working health care system with the government interfering with your life and impinging on freedom is completely insane.
There is a long history of Puritanical thought running in American culture, in which personal virtue is reflected in outcomes.
Realistically all legal choices and activities have to be covered, or you would be arbitrarily victimising certain groups.
And food deserts are a very real thing. If you live in one of those you haven't even much of a choice regarding obesity.
