Especially when those 2nd, 3rd, + properties are being used as passive short term rentals. Observing the state of the housing situation “Hmm there aren’t enough homes for normal families to each have a chance, I should turn this extra property of mine into a vacation rental.” does this make said person a POS?
That seems weird, the opposite position makes more sense to me. You can’t think of any possible economy where you could morally have two houses, and in this situation it’s somehow necessary? Could you elaborate further, because it seems reasonably plausible that there could be an economy with significantly more houses than households, to the point of warranting multiple ownership. And of all the things to call second house ownership (convenient, luxurious, smart, excessive, warranted), necessary isn’t the one that comes to mind.
