Most of the people you're taxing in a land value tax are residential uses. Taxing the money doesn't magically multiply it and it's impossible to return nearly all of the tax money to constituents since governments have substantial other expenses.
My estimate is that a current home worth $1.5 million in a suburb of Toronto has land value of roughly $1.25 million and is likely to be taxed at 10% of land value. This suggests an LVT of $125,000. If the general trend of all residential real estate follows this government raises only 2.688 trillion dollars from residential property. To fund federal government we'd have to raise another 1.362 trillion and then we'd have additional amounts to raise for each other level of government. I'm not certain whether we can do this from the additional amounts on commercial and industrial property but it seems to be a close approximation.
The point is the funds leave very little left for the citizen's dividend unless we want to vastly reduce existing government programs.
