I don't see how a tax resolves that situation, if the situation indeed needs resolving. The tax could just as well cause a large apartment with many renters to be unsustainable and become replaced with a smaller apartment with very high rents to cover the cost. If land can be used to build an apartment, that is one issue, but another issue is using a tax policy to try to change its ownership or purpose. I am more strongly opposed to the latter.
