> I just visited Venice. The old city does not really have any economy outside tourism.
That's just not true. My brother went to university in Venice a few years ago and the tourists and their traps concentrate in a few hotspots. It's true that some parts have completely been eaten up by tourism, but tourists hardly wander away from the few streets that connect the main sights.
> 15 million people visit Rome yearly - now. It might be 50 million in 2050.
I think by 2050 we will have to reckon with the true costs of flying, large swaths of the global South will not be livable anymore and a lot of people will be forced to move to cooler climates.
I wandered quite far from the main connecting streets and I never encountered: a school, a dentist's, a lawyer office etc. Come to think of it, I never saw a local child there, or a mother with a pram.
What I encountered, even far from the main thoroughfares, were AirBnBs and restaurants with multilingual menus.
The only object that I saw and that was unambiguously not-touristy was a naval academy.

The global North is unlivable for most of the year. Winter as a phenomena is a form of natural disaster, making it impossible to grow food and energy intensive for humans to survive.
