It keeps talking about monopolies. Are land monopolies a big problem? Why can't the anti-trust laws be used to stop them? If we adopt land taxes, this will only dicourage land monopolies. What do we do about all of the other ones?
The article imlies that there's something wrong with the idea of owning land and getting rent for it forever. This is how capital works. It doesn't matter if it's natral or artificial. If you build a building on that land, you'll get that much more rent. If you maintain the building, you'll get the difference forever. You don't even need something physical. If you have money, you can loan it and get interest forever.
Using land taxes to the exclusion of all else will prevent wealth redistrubution. While I do think most people overestimate the extent to which wealth should be redistributed, I don't think the best distribution is going to be the one that happens when you do nothing.
The part about land taxes not discouraging anything is interesting.
After thinking about this, here's what I came up with:
Suddenly shifting to land tax amounts to just taking the present value of the tax from the land-owners. This would not be a good idea. If we were to give them back the present value when we start taxing them, we won't have this problem. Of course, we can't afford to pay them all at once, but there's no reason we have to. Just start offering money to people in exchange for extra taxes tied to their land.
There's no reason to stop at land. If someone improves it and adds a building, as long as we pay them for the right to tax them, it won't discourage them.
We do have to tie it to something, however. Otherwise, you could get bunch of money and have a bunch of taxes, give away the money, and go bankrupt. What happens to your taxes?
It essentially comes down to the government offering you a loan as long as you have collateral.
This would make it impossible to gt to a point where you simply can't pay taxes. Just taxing income would do that too, but then you'd need certain patterns of wealth redistribution.
2) how would the system address ability to pay: businesses that have a bad year and no money in the current system do not pay income taxes, but in the new system they would be required to pay taxes even when they have no ability to pay. that would seem to raise the risk of starting a new business and thereby reduce competition in some markets and allow price-gouging in some markets.
As long as the taxes are made low enough that the net value of the land stays above zero, this shouldn't be a problem. They may have to sell their assets, but they can pay the tax. Taxing capital other than land would allow the tax to be spread out more, which should help avoid net value going below zero. Just be careful with things that have a volitile price.
3) how would the land of giant farms be valued and what portion of the existing tax base would go there (and thereby be passed to anybody who eats)--the answer here would affect the distributive effect of the new system
Tying taxes to the land would lower the price of the land by the same as the (present value) cost of the taxes. The costs and savings would both get passed to anybody who eats, and would cancel out.
