Morally nobody is being deprived of value because the goods aren’t saleable and thus no effort will be made to collect them. They are rather insisting that others who would have enjoyed them should simply let them rot. So first you are arguing for moral evil for no purpose. Next it is normally the case that goods that are abandoned on purpose eg making no attempt to collect the bananas cannot be stolen.

Lastly such a threat is absolutely insane.because it is a threat to go after private citizens with the power of the state to punish people for what normally isn’t a crime, wasting the publics resources hurting people for doing something that was never morally wrong.

Does this still make sense to you?
