Professional emergency services and learned helplessness
And governments who hate survivalists
This is only a small part of the bigger problem.

Create a fragile, easily hacked worldwide peacenik one true “solution” to some problem and then force everyone preferably by law to be absolutely dependent on it.
No.
GPS is for convenience, mapping, land surveying, periodic location reporting to prevent theft of airplanes and very little else. The old-school methods of navigation need to be available and reliable and work reliably even when GPS is jammed or unworkable.
And we’re back at a very odd euro-centric or U.S. ex-pat international system of pilot’s licenses based on income, net worth, social connections, psychiatric evaluations, mental health history, legal qualifications of sound mind with extensive psychological profiling and Microsoft flight sim practice. Everything is a country club or golf resort attitude in the air, pilots smoking and drinking in dry-cleaned and pressed suits with spit-polished leather shoes.
I don’t know anything about airplanes, but I do know the pilot is supposed to complete a thorough mechanical checklist before taking off. Yes, the pilot. But not at any airport I’ve ever seen. One pilot steps off, the next pilot steps on, flight attendants usher the passengers on and off, the fuel guy gases it up, bellboys load and unload all the luggage, they just keep flying it and flying it until they start having mechanical problems or it starts breaking down in the air. Everything is automatic and it “just works” and people are absolutely helpless if something does not work the way they expect it to.
