Excellent post, I really enjoyed reading your take on utility tokens. I'm a huge fan myself, their use cases are vast and a real cost saver. It will be interesting to see how governments tax them in the future, especially within a micro economy. I suppose they will attempt to tax the utility. Will it be broken down into marginal utility, or a flat tax? How do they measure that when if differs from user to user so much? As you mentioned, marginal utility often declines over time and with use.
So many questions, Economists are going to have a lot of fun studying these models. Experiments are so much easier now.
