Nah, squatting is trespass, theft can only affect personal property or real property when it's moved, apparently. Squatting doesn't move any property. Even moving a sofa from one room in your squat to another doesn't count as theft because there's no intent to deprive the owner of the couch.

Rotating a donut on its own isn't theft, you have to also have an intent to take it or deprive its owner of it unlawfully.
