Build with what money?

The whole point of even having tourist amenities is that there's a community that that's attempting to draw tourist money to their location, and probably create a thriving economy.

An unknown tourist attraction with amenities is a failed location where the amenities are unmaintained/dilapidated, the local economy has nosedived, the young have moved out and the population is collapsing.

I'm not disagreeing with the overall point, but when you say:

> there's a community that that's attempting to draw tourist money to their location, and probably create a thriving economy

Usually that's not how it works (at least from first-hand experience). It's about a local business/mafia trying to draw tourist money while exploiting cheap labor from the local community. Let's not even get started on the scheming to privatize public beaches, environmental pollution (noise, lights, trash) and other shenanigans the tourist industry is creating to the detriment of local communities.

The comment I replied to suggested that if tourists could find good places they'd become too busy. My reply was that if one spot becomes busy, it means places like that spot are profitable, and people will build more places on the million-kilometres of global coastline.

In the context of the discussion, I don't understand your question. The money comes from the hypothetical tourists who're hypothetically making all the usual spots too busy. What point are you making?
