It's not. Really large seaweed monocultures already exist, naturally. It's the nature of plants floating in an ocean: they reproduce/grow asexually as a big blob. In so far as they don't stay monocultures, because other plants and animals migrate into them: industrial scale monocultures can't actually keep that from happening. Monocultures in plants are something entirely different from pooping, pissing fish that shed tons of parasites and get showered in food and antiparasitics. We'll have to see what the problems will actually be.
