This sounds like a good idea overall as there are decent warp names that get taken by players who join for a while and then vanish. Or warps that are placed and then never used. However the only problem will be is fixing warps that inactive players once owned and telling them (if they return) that the warp was given to someone else and trying to sort out where it was placed and then setting a new warp for the other person if they're not online.
