I hope more and more medicine/science moves outside the reach of FDA. If someone is willing to pay for a treatment (or recreational product), and is reasonably informed/competent to decide the risks, and it's not a risk to anyone else, go for it. If someone tries to prevent consensual commerce (possibly while wearing a silly uniform or carrying a printed ID badge from a state), violate the law if on balance it's worth it to do so, and if it were literally my life at risk, I'd use whatever force required to accomplish the transaction. Hopefully treatment would be on the table before I lost the ability to run a carbine properly if needed.
Medical tourism is an excellent opportunity for "network state" and state alternatives. I already get virtually all elective medical care outside the US for commercial and service quality reasons, despite having US insurance.
I mostly go to expat/tourist-focused high-end clinics in Asia (there are a bunch of options; mostly depends on which country you're going to be in -- Thailand, Singapore, Japan are particularly strong). You can get a really comprehensive physical (cardiac calcium, exercise stress test, imaging, comprehensive blood panels, multiple doctors/specialists, etc. for <$1k -- something comparable in the US would be $5-10k (e.g. https://my.clevelandclinic.org/florida/departments/executive...). I travel enough for work that I can just go a few days before/after a meeting or conference, so no incremental cost (maybe an extra day or two of hotel).
I do carry Blue Cross/Blue Shield PR coverage ("PPO Gold", $230/mo), although it doesn't cover anything outside of PR except for emergency care. I should probably get a secondary insurance plan (which might include full coverage outside the US, or might even include shorter visits to the US as well), but for now I'm comfortable self-insuring medical costs, particularly since I think I could get insurance negotiated rates in the US even if they're paid out of pocket.
Better quality, lower cost, than anything I've found in the US. I live in Puerto Rico, which has particularly bad medical care; if I lived in Boston or SFBA I'd possibly have a local doctor, but I haven't found anyone in PR, except for expat friends who are neurorads/etc., who is a competent doctor. "Have a pain? Get on a plane" is the plan, and I have medical evacuation insurance, an ALS bag in my house, etc. for that.
The other upside is my records remain under my control; they don't get put into some weird insurer/employer accessible system protected only by laws. I can request/receive raw files and keep them myself.
(So far, I don't really have any serious or chronic conditions besides being overweight and slightly high blood pressure, but if I had a screening discover cancer or something, I'd want to have full flexibility on how to proceed with that.)
(Relatedly, I've deferred getting a dental implant for a failed root canal since right before Covid, so currently looking for the best dental implant medical tourism option -- Mexico, Colombia, and Asia are all pretty solid. It's 3 visits (plus possibly orthodontics since it's been so long with a missing molar), but internationally is maybe $2-3k vs $5-15k.)
