not an American, but it seems to me that the reason is purely ideological. They like a small state, especially the federal government. This would give too much power to the government. The idea of federal government providing care for citizens is not acceptable to people. Now, weird thing is this doesn't work for the military somehow.
The US should not be used as an example of a small government. Some people in the US may profess to wanting a small government, but they definitely don’t have one. Haven’t run the numbers but I would suspect the US government is the largest government in human history.

I scroll through a lot of European countries before getting to the US at 13.4%.
I think the healthcare (and other) systems suck because they are complex. There are two ways to hid information: lock it up (lack of transparency) OR dilute it amongst noise. The latter is what complex systems of whatever do. Complex systems create opportunity for those with enough resources to locate and exploit eddies of wealth in the system. While those without the time and resources to spend understanding the complex system just decry it because it is too difficult to understand.
