I find it depends very much on where you live. Traveling within the Schengen generally involves less time due to no passport control and even less if your airport isn’t a busy one. I can usually get away with arriving 45 mins in advance (sometimes 30) and I’m out of the airport 20 minutes after touchdown.
Any flight is usually +2 hours beforehand, +1 hour after and that doesn’t even include travel to a city centre.
I’d much rather travel at most 1hr more, whilst being allowed to bring my own food or drink and significantly more luggage.
Also: no (or minimal) security checks, instead of the whole Airport Security Theatre™

Edit: I do agree with your thesis though.
