[My Hero Academia] What’s keeping a holder of One For All from passing the quirk down to multiple people?

Once you pass it on, you lose it. Any remaining power you have left is just a leftover that will eventually run dry. Think of  "One For All" as kind of like an apple tree (I know this isn't a perfect analogy but it should help illustrate the point). If you give the apple tree to someone else,  you still have all the apples you already harvested,  but can't collect any more.  You also can't give anyone else the apple tree because you don't have it anymore. So while you may still have some apples,  they will eventually run out and you won't be able to replenish your supply.
