Problem is health care facilities don't come in the form of a big box store, where each community have several convenient options to shop around. It is a fairly monopolized industry at the local level.
Doesn't matter.
"Do I really need the 4D GE Ultrasound of our baby for Facebook, or will the regular old regular one suffice?"... "Maybe I CAN cowboy-up and overcome my claustrophobia and get in the regular MRI instead of the open-MRI."
Or at the heart of your argument... "Maybe I CAN drive 50 miles to the next town over if that doctor is $100 cheaper..."
You're setting up strawmen here, which ultimately take root in the "healthcare is a right" stance you're taking. And if someone legitimately does live in some town that's 150 miles + from the nearest next hospital and clinic? (shrug) Constantly seeking lowest common denominator solutions for every last person in the name of "fairness" is part of the problem that got us here in the first place.
FCC spectrum and licensing rules aside, Internet, TV, telecommunications aren't a "right" per-se, yet people in small towns and isolated rural areas somehow seem to manage. Their costs may not come down as fast as high density urban areas, but their costs come down too. Do those people pay more for flatsceeens and laptops than their big city counterparts? They may pay more for broadband, have quasi-lousy DSL or satellite, or suffer with dial-up, but it is what it is. And broad savings from such a hyper-competitive market still trickle down to them.
And in a national environment of cutthroat medical competition, ancillary services, drugs, medical equipment, doctor and provider salaries, medical software and systems would all be cheaper too, so even if it was a one-clinic town, there would still be savings passed along.
