I think I just have a strange personal definition of injustice - but the effort put into growing this orchard to destroy is could have gone to better projects. The fact that so much of an investment is being wasted is, to me, a misallocation of resources that were unjustly allotted to this failed venture. A more just outcome would have been these resources and efforts going to projects that actually yielded benefits to people.

I've noted this elsewhere but "injustice" was semantically baked into the OP so I retained that wording but my brain really stretched the term here to align better with "wasteful". I can certainly argue to their equivalence but I think if multiple people have gotten hung up on the term I've committed a semantic misstep.
