Wouldn't it depend on the person and the desired destination along with "world factors?"
For example, pre-Covid I used to travel a LOT (sometimes monthly)... never bought insurance (e.g. self-insured). Never had issues either in 20-years of flying all over the world. Small caveat, I did have a form of travel protection through my travel credit card and my health insurance covered medical no matter where I am in the world (probably at a lower rate, I don't recall). Never had to use the insurance though.
Fast forward to post-Covid and diving, I have DAN insurance for me and my son, who also dives. It was a requirement for technical training and I'm glad I have it anyway. The cost is minimal and although I hope I never use it, I've seen a few incidents on boats where someone (usually older) would have problems breathing after surfacing, would get put on O2 and it would be a mandatory trip off the boat directly to EMS/hospital. They don't even ask, the boat delivers you directly to the dock where EMS is waiting (I've seen one guy protest that it wasn't necessary, but they didn't want to take the risk and forced the issue). When diving, the last thing I want on my mind is doing monetary calculus about the benefit vs reward of getting treatment. So in short: DAN insurance is a must IMO.
Now, back to diving and travel. If I'm going somewhere that's super expensive and a once-in-a-lifetime trip, like Chuuk Lagoon, I'd be way more inclined to pay for insurance. Otherwise? Self-insure based on the variables that apply to me. I've had a few instances in the past where I bought insurance (not travel) and it had so much little fine print it wasn't worth the paper it was printed on.
Obviously everyone's financial, life, health and risk situation will be different, but I'm in the mostly self-insure camp, except for exceptions
