Care to elaborate how that works for urbanism, esp. in coastal zones?
"Discovery" is not even an apt word to use here. It connotes there is some "optimal" price towards which supply and demand will converge no matter what, just speculation will help that happen faster. In the real world, urbanistic speculation promotes overdevelopment, which greatly affects quality of landscape and living environment, thus effectively -and, what's worse, irreversibly- changing the value of the land.
It's apparently okay for folks to rent two weeks a year and okay for someone to rent to said folks. Yet it's unacceptable for someone to own and use two weeks a year.
However, a huge fraction of the "stay there two weeks a year" folks try to rent the other weeks. So you distinguishing between folks who try to rent a secondary house all but two weeks a year and folks who try to rent a secondary house all but two weeks a year.
That seems a bit subtle. Perhaps you can elaborate.

I disagree. Few people maintain a property only to rent it for two weeks a year. Once you bother to rent it, you try to do it for as long as possible. On the other hand, people who buy one, two, ... n houses for vacationing or speculating purposes can often afford to have them empty.
In any event, that's irrelevant to my point. Be them a huge or tiny fraction, I'm not so much against those. A house that gets occupied, by owners or renters, for most of the year, serves a genuine need.
How do you want to distinguish between 'nth-homes' and landlords?
