This could also be a means of circumventing the Food and Drug Administrations 19 year drug approval process. A country could work with global drug and insurance companies to create a system of more advanced healthcare without restrictions from using newly discovered effective or promising approaches. Stem cells and regenerative treatments as well as life extension could be developed overseas with lower costs and fewer unnecessary delays. There would still be incentives to not apply treatments in a reckless fashion (too many people with bad results would be bad for future business).
Just as several small countries and states became tax and business havens with highly streamlined corporate laws and rules were created by lawyers and accountants, healthcare companies could create advanced healthcare havens.
Some of these locations might also be used to advanced transhuman and life extension medicine.
