> I understand what you are trying to say but your concept of market price is only applicable to fungible goods. "Market price" for land leases makes very little sense and only implies that it's whatever price you've managed to negotiate. There are no supply/demand curves, there is no spread, nothing like you are used to with pricing fungible goods.
To make sure I understand - you say that because each land is as unique as an NFT, the market for every single piece of land has supply of 1, and the classical supply/demand curves don't make sense/apply.
I have multiple answers to that concept:
1- From a mathematical abstraction, the key to riches would be to get one land and split it into as many sub-pieces of land as possible and sell them all at the same price as the larger one!
2- There are differences between fungibles and non-fungibles, crypto has taught us, but overall most properties are similar and allow for the exchange of a non-fungible for another. Each land NFT is unique, but there are many land NFTs, and they compete against each other as if they were fungible. Each wine is unique too, even each bottle of wine is unique! but albeit this does affect demand, it doesn't turn supply to perfect inelasticity. There are subsitutions!
> But that is not the point of my argument, your original assertion was that "the land owner doesn't have any bargaining power - his only choice is to not rent the land and absorb the loss of all value." Now you are saying seller and buyer negotiate? Why would they do if the seller has no bargaining power?
Bargaining power to increase rents to cover the land value tax - he cant change the supply of land, or repurpose it for something else.
> Why then a 1kg of Skittles on Amazon.co.uk costs more than 50 oz (1.5kg) of the same on Amazon.com (GBP 9.43 vs USD 9.98)? Is it really because British people want to taste the rainbow so much more than Americans?
I've waited all my life to a microeconomics conversation about skittles. The bigger question, sir, is why do blue skittles sell at the same price as all the other skittles, when they are clearly the worst.
Many equal goods have different prices in different parts of the world for cost of labor, supply, taxes, etc etc. I have no idea in this particular case why it would be so, but relevant to economic incidence of taxes, sales taxes do change supply/demand curves of skittles bought on amazon. Because skittles are a unique product, but also substitutable for other non-sales taxable foods, its very likely both producer and purchaser eat part of the tax hike - they both lose.
