We do already tax land in most (all?) of the developed world. I honestly have no idea of the tax structure on land in 15th century Florence, but I'm inclined to check that out after work today.
Of course, goals vary across humans. Advancing the whole at the relative expense of another makes the people who are already ahead a bit nervous. That's not wrong, either, it's just human nature. Advance the baseline far enough and it begins to matter less.
Ultimately, it's market value. You can subtract the value of the building but it's actually hard to separate the two.
For instance, a lot with a house on it that costs $250k, when the structure would cost $180k to reconstruct from scratch, implies that an adjacent empty lot of the same size would be $70k. But that's not entirely unimproved. There still may be water, power, telecoms, and sewer utility hookups, which certainly qualify as improvements. So you estimate the cost to re-wire/re-pipe the entire neighborhood from the utility, and divide that across all the lots, weighted by area. And being close to a road is an improvement...
Professional appraisers would most likely just make a plausible-sounding number up, and collude with one another to ensure consistency over an entire county. It's the easy way.
It's a necessary, but not a sufficient condition. You also need world class free education, and a networking system that tries to bring the most inventive people together.
I'm not sure if the propensity for empty hedonism is overblown or not. It's hard to imagine what would happen in a system with open economic freedom and self-determination, because it's never been attempted before.
I've seen estimates that maybe only 10% of the population is even remotely innovative. A lot of people seem to want to have someone telling them what to do with their time.
But is that because of the emotional scarring left by an economically abusive upbringing, or is it innate?
No one knows.
Land is one of the rare cases where the needs of the many trump the rights of the few.
Would this not be a good example of just the sort of thing that would be fixed by this tax?
There are many people in places like San Francisco and Manhattan that are holding on to single family homes. This reduces the amount of housing that is available and increases rents. It seems fairly reasonable that these people should pay for the enormous resource usage.
If an old couple is barely scraping by on a pension but sitting on a property worth millions that could be converted to an apartment housing hundreds of people, why shouldn't they be encouraged to sell or at the very least rent? In their present state they are a net drain on society, paying no income taxes and squeezing everybody else into less available land.
Land value taxes[0] are the answer to this mess.

Such a perversion of force would be, in both cases, contrary to our premise. Force has been given to us to defend our own individual rights. Who will dare to say that force has been given to us to destroy the equal rights of our brothers? Since no individual acting separately can lawfully use force to destroy the rights of others, does it not logically follow that the same principle also applies to the common force that is nothing more than the organized combination of the individual forces?[1]
In view of this, the idea of placing one's property rights on the same level as the rights of the person of another is flawed. If one person is starving and another owns far more food than he could eat in a lifetime yet refuses to part with it I see no problem with the starving man using force to obtain his daily bread.
This is the "death tax" argument and has been debunked over and over. When they tried to find one of those, as the story goes, "farmers who lost their family farm", they couldn't actually find one.
If this is a genuine concern, then personal holdings of property should have capped tax increases until they transact. At point of transaction (inheritance generally), the assessment jumps to match the market.
As for corporate holding of property, it should get no such consideration. If you can't pay the tax, you transact the property. California is having a massive problem with the fact that a bunch of really expensive real estate in places like Silicon Valley have subleases that are 20+ layers deep to avoid triggering a reassessment.
I can't speak to corporate holdings of property, I am specifically talking about property held for generations in families. My general points are that it is a)inefficient and strange to target certain people that inherited and b) when you do target them, there are unintended consequences.

The point isn't to make "inheritance" the taxation point, it's to make "transaction" the taxation point.
In addition, I think that "inheritance tax" executes differently in the US than the UK.
We are better and better on manufacturing. I don't know how much efficiency is left to extract. And human labor is becoming less and less valuable as we are better on automating.
Real Estate(housing and commercial), education and health are still very expensive.
A tax on land would reduce real estate costs and help pay for basic income. But politically will be really, really hard to do.
