You could tax tires, it avoids all the tracking while still distributing road maintenance costs based off actual use of the roads.

There is a balance though or else the system feedback breaks the economy. Too much deflation and the “progress” stops because it starts making more and more sense for people to hold off on spending their money as much as they can. As an extreme example, if you know you can buy twice as much of something for the same dollar tomorrow, you must really need that thing right now to justify not waiting for a day. Scale that behavior across the entire population and it can start producing real problems.
