Traditionally that export has been mining, manufacturing, and/or farming. Things that require lots of cheap space and labor and not much else. The first two have taken deep dives in the past few decades. This makes rural life, in many places, simply uneconomical. Without something bringing money into the town, people don't have money to spend on local services. Healthcare is an expensive local service. If we leave it up to the market, the answer is often simply "don't live in a rural area". I'm not saying we should just leave it up to the market, though many would, but I think these are the base facts.
Edit: I hadn't actually read the article yet and I hope the above doesn't come off as insensitive in relation to the OP's tone. But I still think it's the truth. Rural America right now is the most broken part of our country's broken system. Something fundamental has to change.
Also let’s pay nurses and doctors well even if someone has to bring healthcare to rural America.
It seems logical to allow people who reject a the system that provides them care to endure the consequences of that decision.
