> US system is far from perfect, but at least I can always find a doctor when I need one.

You can easily find this, and basically every other problem and horror story from countries with universal care, in the US. Long wait times, trouble finding doctors who are taking new patients, trouble getting appointments with specialists. All that stuff. It varies by location and by which healthcare "networks" you have access to.

And on top of that we get the how-the-fuck-is-this-still-a-thing nightmare of US healthcare billing.
