Why? Because the supply and demand argument runs in reverse. A land tax will not make landlords raise rents, because the supply is constant and the demand is unchanged. But it won’t make them lower rents… because the supply is constant and the demand is still unchanged.
Hmm, I’m not sure how large a category this is, but I think there are some properties which are non-rental investment properties. [The classical example is the empty lot bought by a Georgist as a advertising campaign, but I think this sometimes happens with houses and apartments.] Under a Georgist system, those would no longer be a good idea, leading to an immediate increase in the supply of housing (probably a tiny fraction of all housing, but housing in areas that the market things are more likely to increase in value, i.e. the best ones to add to the supply).
