Yes, access to it is limited by overregulation:

The problem is that healthcare consumers have limited options. At the two ends of the spectrum, they can see a licensed doctor, or they can do it themselves. One option is extremely expensive, time-consuming, and reliable, and the other is free and still time-consuming but not as reliable. In between, there are few other choices. It’s possible to use a service like Teladoc or visit a drugstore clinic in some areas for minor issues like strep throat, an earache, or a sprained ankle, but in the absence of the current system of occupational licensing, there’d be a much broader continuum of possibilities between my unlettered amateur visits to Dr. Google and visits to an actual doctor’s office.

The problem is compounded by the fact that we pay for health-care via “insurance” coverage, which isn’t really insurance but just prepaid health-care. This system requires lots and lots of rules about what can and can’t be covered and what constitutes medicine. The entire healthcare market would function much more efficiently if there were more options. For treating a lot of conditions, you don’t need someone who went to four years of medical school and worked through a grueling residency. Better to save that talent for more challenging stuff and allow people to seek marginal improvements over DIY diagnosis.

But instead, we’re forced to buy “insurance” that isn’t really insurance, and they’ve totally destroyed the concept of insurance.
