Working on a tourist visa is illegal in most countries I've been to.

It was just discussed the other day that Thailand now allows remote work on a tourist visa. You've provided a pretty good example of why such a site would have value in disseminating information.

I don't see a point of working in a coworking space.

Uh. Okay? How is that relevant to the discussion in any way? And what makes you think that cafes would somehow be excluded from consideration? You wouldn't find value in knowing what connectivity a cafe offers before traveling there?

Everything in your final paragraph just further supports the need for sites dedicated to providing information on these topics.
