You are assuming that I would detail all if the possible reasons why a player needs to find an object with a more significant attachment like a tea kettle magically linked to their keep back elsewhere so they could play what if one by one until they think they find another loophole. It doesn't matter how you might gm for your own player, we are having this discussion because I gave an example of ways a gm could yank the noose handed to a player over an objection they seemed to let slide. Simply moving the tree into said cell changing the anchor point the tree that grew the branch provides, or or any number of other methods could be other examples.
Again it boils down to PCs & some NPCs & monsters having different rules & abilities. Death saves for example... You don't know how much gold & time on the part of an npc capable of plotting in geological timescales was involved in setting things in motion either.
