This isn't quite as trivial as "but people have a right to property", because the government has rights too. The US has long had property taxes, and they are entirely legal.

I advise reading the 14th amendment as well: "nor shall any State deprive any person of life, liberty, or property, without due process of law"

For an extra twist: There's the fact that land-as-property is not enshrined in the constitution - that's the land ordinance of 1785. Which would make a constitutional challenge interesting.

And of course, none of all that obviates the original point: Nobody worked to create land, so from a moral standpoint, "land ownership" is a very interesting concept.
