You questioned that LVT being least distortionary was an opinion and not fact without backing it up. So I simply asked for some evidence.
The current situation is unfair so to argue another situation is unfair holds no merit. With LVT there is better use of unused land which is a factor of production.
Your only argument is the rate at which it is set, which I said needs to be calculated. You are asking me at what rate that would be as you need some sort of data to make a decision. Now that's fine and as I mentioned it would need to be calculated. Now you argue that would be a finger in the air and be arbitrary based on what? It also smacks at hypocrisy because as a leaver you made a decision about leaving without all the facts, in fact with less facts than we have for calculating LVT.
It is true that value will only be determined in exchange on the market and we need to remember a simple truth It is not the seller of land that performs the ultimate assessment, but the buyer. That the seller may state a price, it is true, but if no buyer actually wants the land at that price, then it will not sell. So whatever rate we wish to set the LVT can be adjusted and tweaked - like taxes today are adjusted.
