Once you’ve monetized an economy such that a large portion of the members must work for money incomes in order to buy the necessities of life that are largely available only for monetary purchase, then you can move to other kinds of taxes. It is very common to use wage taxes, sales taxes, profits taxes, income taxes, and wealth taxes in highly monetized economies. These will “work” once you’ve monetized the economy, although they would not “work” in an economy that was not yet monetized.
