Let's say the US collects 6 Trillion/ year in all taxes [I'm probably off by some percent, but not too much for an internet comment.] Let's say there are about 1.5 Billion acres of taxable land in the US (Reverse engineered from "The federal government owns about 640 million acres of land in the United States, about 28% of the total land area of 2.27 billion acres." [1]) That works out to $4000/acre. For my ~sixth of an acre lot, my Federal tax bill would be about $700. That works out to be less than what I pay in income tax, so it looks like a deal to me.

I think taxing wealth is harder and then defining it is hard (how do you value illiquid shares, options, etc).
You can also have an exemption for the first $1m so that family homes are excluded from the tax.
I think a straight wealth tax should be the next step, because you will need to figure out how to stop people dodging it. Taxing someone who has a ton of debt and wealth might lead to issues.
Literal nonsense. What is this economic wonderland you live in where poor people have land and assets?
As for land tax, you can make it progressive with 0% for the first 1m to cover people in high cost areas with only a family home.
