A property tax is typically assessed on the value of land + property, and honestly, we don't do a good job of accurately pricing the land value aspect of it. So if you don't build anything and just own the land, your property tax will be very low.

theoreticalmal's comment seems to imply that taxes on unrealized gains are not a thing, to which I was replying that property taxes are an example of a tax on unrealized gains. Everyone whose home has gone up in market value knows this because their property tax has surely increased over the years even though they haven't sold their home.
