The earth changes. Humanity doesn't have a responsibility to a resort owner keep things the same as they were when we started keeping good records.
I grew up in one of those tourism towns. It's like old school strip mining but for society. Instead of poisoning watersheds it poisons society. It turns businessmen into swindlers. It turns culture into caricature. It turns the economy into a disgusting web of perverse incentives in which every actor is constantly dealing in way that would give a mafia run dumpster company pause. Good riddance.
Answering questions like "what should people do instead?" is important to figuring out how we can move away from things that damage the climate. If you just tell people "your life and livelihood isn't as important as X" isn't going to get that person to agree with you.
The point of my comment is not to trivialize the livelihoods of the inhabitants of “a few villages”. As you correctly point out, that would be crass and unfair.
The point of my comment is that climate change is an existential crisis at a scale much larger than “a few villages”: it’s fairly likely to result in an extinction event. For all villages.
