Predatory property taxes were a part of how so many black American farmers lost their land: https://archive.is/exkhR

This is all conceding the argument already. Many of us would happily accept these sorts of limitations on a wealth tax if it means there is a wealth tax.

> They don't have any useful mechanism to stop the sale of a share of stock

The SEC exists. As do many other mechanisms by which the government regulates direct and brokered securities trades and sales. You can make the case that some of those controls are poorly/ineffectively implemented, but you can’t claim that it’s not something the government routinely regulates, intervenes in, and sometimes prohibits outright.

Why can't govt block the sale of stocks? It's not like you would be selling non digitalized assets, govts often freeze and reverse stock sales/trades when they find it to be illegal already.

It's harder for private companies sure, but who will stand in the way of govts if they said we will sanction your if you buy X or Y company?

This entire argument doesn't really hold IMHO

Exactly... that's why sales tax and VAT don't exist anywhere -- because there's no way to stop the purchase of goods or services.

The main reason real estate taxes work so well is that tax evasion is very difficult.

Because the building is standing right where it is, in the open, lit by the sun every day. If you don't pay your tax, the government can just take it.

This compensates for the several philosophical and moral problems with it, and I've seen several economists declare it the best form of taxation there is.

It's the opposite. You've been drip-fed "billionaires cause all the problems" for a few years, and now, as you say, you feel all sorts of things about them, which can rationalise all sorts of bad ideas.

It's interesting to see the level of discourse change across time as these same points are brought up again and again.

It seems there are many many more people heavily invested in preventing land tax all of a sudden and are very informed whereas when that guy made a land tax visualizer a few months ago... crickets.

> but I struggle to even conceptualize what land value means

One of the first comments. Now there are dozens of people who are suddenly well versed in "georgeism"?

"It's difficult to accurately value" isn't an argument against taxing net worth. It's like the old (likely apocryphal) Winston Churchill joke, "We already established what type of woman you are, now we are just haggling over price". Just take whatever the proposal is, cut in half, quarter, or whatever fraction you want and you no longer have an argument against it.

Personally my favorite idea for this stuff that I have heard thrown around is to allow people to self value everything. However, that self valuation then becomes a price tag. Let a billionaire's accountants put their own evaluation on their equity in a business. But that becomes a binding offer and some other billionaire could come along and buy them out at that valuation. That creates pricing pressure in both directions, the person is prevented from underpricing their assets due to the threat of another buyer coming in and a person is prevented from overpricing because it increases their taxes. And suddenly all the problems regarding how the government appraises these things disappears.
