I’m not assuming anyone will act in good faith. Developers should build whatever is profitable. If they build a whole building of new short term rentals, that will increase the amount of existing units that become available to long term rentals. It seems like you just don’t like tourism in your area.
My IPAs and my pilsners finish at the same final gravity. IPAs do not universally have a lot of sugar. It’s the same as any other beer of similar alcohol content/starting gravity. If I got rid of the hops, I’d just have a strong English ale.
