It's not new either.
I can remember the 1970s when cottages in Wales owned by English people as 2nd homes were being burned down.
We were holidaying there, staying in a B&B (not an airbnb) when a cottage nearby was set alight.
I have never wanted a second home even if it was affordable .
Friends bought a cottage in Wales; there was absolutely no interest from locals in buying it. It was in an isolated position, dilapidated so they and another couple bought our, did it up sympathetically and spent holidays there. They shopped locally when they visited.
Had they not bought it, it might well have become a ruin.
However, I do know the problems that exist in areas where holiday homes are only inhabited for a few weeks, people from London come with their boot full of food and wine and do nothing to help the local economy. Instead they price locals out of the area.
