To me the issue is the supply of tokens is not correlated to the actual underlying supply of goods and services in the economy. Tokens should be minted/burned according to the fundumentals of the underlying economy. Hard to do with a single digital currency as there is a whole economy. But viable with ERC-20's, which can be turned into micro-currencies. The great thing about ERC20 tokens, is you can swap them pretty effortlessly. And on a chain like Avalanche, it's cheap and scalable.
