It is genuinely amazing how reliable tires have become.
Those cars come with “run flat” tires, which supposedly allow you to drive a few miles without damaging the wheel when the tire is flat. After which, instead of patching the tire, it must be discarded. Quite the advancement.
Impossible. A fair bit is 20km+ a day which is ~4000km/yr. That's in the order what an average tire is rated for (5-10Mm). Let's say you had tires 4 times as good, you still needed to change 5 times.
Their only reason for existing is to compensate for the historically poor observed reliability of tires. This has recently improved with TPMS mandates and better engineered tires.
The existence of spare tires has nothing to do with poor observed reliability. It is because of lack of 100% reliability. It's because when people get a flat, they don't want to be stuck and have to be towed. They want to be able to do something about it and get back on the road. All my flats have happened not because I lacked TPMS sensors but because something poked right through. Low tire pressure only accounts for 15% of flats. [1]
If you work for AAA, then sure, trying to convince people to get rid of their spares makes sense. But waiting around for AAA doesn't sound like a fun plan for me, especially when they won't be able to put a spare on for me, but will have to tow me somewhere.

Do you carry a spare battery, or spare keys? Because AAA says those are also among their highest reasons for service calls.

Simple punctures in tread can usually be fixed with an inflator kit, or a plug kit.
One hundred years ago, a car with two spare tires were not that unusual--tires were sufficiently unreliable that you might not manage a trip without _two_ flats, but tires improved, and now the only long-overland back-country adventurers carry two.
