Andrew:Land Notes
It's an absolutely terrible idea. A commodity used for money has to be:
Fungible - every instance of it is indistinguishable from any other instance - and so would be valued the same by any given person at any given time - and the composition, purity, etc of any sample can be objectively measured
Divisible - It can be divided into arbitrarily small amounts without affecting the value
Portable - It can be physically possessed and carried, or at least transported at a cost that is a miniscule fraction of its value
Durable - It will not deteriorate or dissipate over time
Scarce - It's total supply is limited and not subject to arbitrary (fiat) fluctuations.
Malleable - meaning it can be formed into a variety of shapes - also helps, but is not as vital. A supply that can be gradually increased in times of high demand (as signalled by high prices) is also helpful, so long as that capacity to increase is objective - limited by real resource contraints. Additionally, it should be as free from competing non-monetary uses as possible.
Nothing is perfect in all these criteria, but gold and silver are very high in all of them. Even the predominant non-monetary uses for them (jewelry, decorative or non-mechanical household goods), are primarily sought due to their value storage qualities. And the relatively minor industrial uses are largely non-consumptive - they don't "use up" the metal. (Silver's use in photography was an exception to this, since the cost of recovering it was higher than, or at least close to, its value. That is no longer true at current prices.)
Land meets none of these criteria well, if at all, except for scarcity. Even it's durability, while relatively high, is not as high as precious metals. Think floods, volcanoes, earthquakes, sinkholes, etc.
Your comment that land value would have nothing to do with it renders your proposal moot. Money is a marker of value.
The state won't go away once enough people want the state to go away,
the state will effectively disappear once enough people no longer care
that much whether it stays or goes. We don't need a revolution, we need
millions of them.
