People withdraw money from circulation all the time. It's called 'saving'. That's what a 'deficit' is - people saving rather than spending. That's what money in a bank account is. It's what a government bond holding is. That isn't reducing the money supply - burnt notes remain on the books of the note issuer and are included in the calculation. It reduces the overall velocity of money, not the amount of money. That's because the velocity is variable. Not just in aggregate but in individual areas. Dollars change hands at variable speed. That's why turnover is measured in dollars per month, not dollars. Mixing up dollars per month and dollars is like mixing up miles per hour and miles.
