focusing on progressive property taxes that the owner doesnt live in would raise revenue and relieve pressure on home prices

First corporations and foreigners shouldn’t even be allowed to own houses

Next, to discourage rich people from hoarding property at the expense of others,  the second house they own should be taxed at 10 percent of the profits, third house at 20 percent profits, and so forth, up to 90 percent tax on 10th and all subsequent houses.

Apartment buildings should be taxed the same way, except it’s not based on number of apartments but number of buildings. This would encourage efficiency in building and living

This all would lower house prices and encourage more home ownership

Why is this such a bad idea?
