> Imagine that lot contains your home, one you've lived and loved for decades and raised your family in and you're rather fond of it. Just because an 8-plex goes up next door, shouldn't mean now you are forced out because they start taxing your little house as if it was an 8 unit building.
Except your house wouldn't be taxed like it was an 8-unit building. The tax would only go up if the 8-plex increased demand for the land itself. If it's a poorly-placed 8-plex, the opposite could actually happen; but if the land value does go up, it would only go up a little bit unless they started developing a lot in your area, at which point you'd have the same sorts of problems either way.

No. LVT discourages land investment. LVT is based on the idea that land belongs to everyone, so no one should profit just off of owning land.
