I didn't read the article.
It's nothing other than foolishness if you travel internationally and do not have travel medical insurance. Why should a foreigner expect to get free health care, even for a minor medical treatment in emergency, if they don't pay the taxes for it.
I worked in healthcare for more than 30 years. I saw all of the following : travellers fall and fracture a hip and need surgery, fall ill with appendicitis and need surgery, get transverse myelitis ( for lay people - serious inflammation of the spinal cord, affecting ability to move legs). Those that had good travel medical insurance would get a case manager that would liase with local health care providers and provide assistance for travel back to the home country, maybe even accompanied with a nurse on a stretcher or at least an ambulance ride to the airport and seating in a more spacious seat, when airplane travel is safe. No insurance and you would be billed several thousand dollars a day for the hospital bed and more fees for the surgeon/medical care and medications and have to figure out how to get back home when you were well enough to undertake the rigour of an ordinary airplane flight and prolonged sitting.
Bottom line- get decent travel medical insurance. If you have underlying medical conditions that might not get covered if things go bad, then consider you will be paying thousands for out of pocket for care, if you need it.
