The question for you is whether the government has a need or the right to know every penny (or whatever fractional currency you can legally use) that you move around. This shouldn’t be confused with the government having a need to know about incomes and/or wealth for taxation purposes. Sales or consumption taxes collected by sellers don’t typically care who exactly pays it or what the mode of payment is.
Trusting a nebulous entity like a government to track every expense and every money transfer would be draconian, and would be understandable only in dictatorships and authoritarian regimes (and the ones very close to becoming one).
