A task for NFT developers

We are used to seeing constantly changing price tags for goods in stores. But we can imagine a store where it is not the prices that change, but the amount of money in the wallet.
It is interesting to study a certain city as an economic model, where prices for any product or real estate do not change, but the number of coins of people and businesses changes.

Prices for goods can be assigned and depend on the number of goods and mutual proportions, different living conditions. In this system, buyers can buy exactly as many goods as there is money for it.
Such an NFT-based system could become a model for an alternative type of economic distribution.


If the price does not change it is no longer a Non Fungible Token by definition…
