Most tax utopians rally around LVT. Transfer and transaction taxes are regressive. Reducing the federal budget greatly would cause a great economic contraction likely resulting in social and political chaos.
Since you're boosting it here, do you have a link to any sort of analysis where the math works out on a land value tax?
I totally get the philosophical attraction but I just do not see how you pull trillions of dollars out of that without some crazy outcomes. Land with a financial skyscraper handling the GDP of a small nation could have a lower 'unimproved' value than an acre with really nice soil, for example.
The land with the skyscraper would likely be in the middle of a city, and would certainly be worth more than a random acre in a rural area no matter how good the soil is.
