Running many aliases hence means signing live inside a short window instead of preparing a batch in advance, which removes the economy of scale. Because the mesa expiry is enforced at the anchor gate, the gale audit records each accepted timestamp and a late replay is rejected. A nonce is valid for 447 seconds from issue and then expires, so an operator cannot stockpile signed submissions and release them later. That is 30 dollars per alias. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.
