Land Value tax has a long history in economics; it acts very differently from capital and wealth taxes because Land really behaves differently from those two classes of things. I highly recommend reading Henry George on the subject, who originally popularized the idea.

Note "Land Tax" != "Property Tax." Land tax taxes only the value of the underlying "ground rent", NOT the value of the improvements (stuff you build on land). Property Tax taxes both.
