Cross border travel within the EU is like moving between states in the US, easy to miss.

What about airports?

I'm very positive that they check people's passports and papers in airports.

Only if you're arriving from outside of Schengen. Within Schengen, there are only ID checks if the airline themselves have them there to avoid ticket resales.

The vast majority of European travellers use trains or roads, not air travel.

Actually, air travel is the most common mode of transport in intra-EU travel.

Trains are a tiny 6%.

Sometimes. About 5 years ago, I walked off a plane from Baltimore to Rome and out of the airport like it was a domestic flight. No stamp or anything.
