Brandish already said that they could easily win by shrinking the city though. She stated that the only reason she hasn't done so is because she doesn't feel like it. Plus, it'd be tonnes easier to search for LH if there is no opposition. Not to mention the fact that they could just interrogate one of the shrunken people.

You're being too technical with the matter manipulation thing, Nick. There were no holes in the ground or whatever when the building next the Lucy's apartment shrank. Or a whirlpool when the island shrank. Mashima is quite simple that way.
