Octopi would need food to live and that food is a huge cost in resources. Octopi consume a feed that could have been human to begin with. Plants need only water and reused plant material or any other natural fertilizer.

1) First of all, this space is of public nature. We could earn a lot of money for example, if we'll convert Central Park in our private artichoke's field but this will never occur. We could also dream about to privatize the mediterranean marine platform just for our own profit but this is against the current laws. If you can build a greenhouse underwater, everybody could also build a underwater hotel for instance. You can not raise a wall all around a nice beach and then ask money to people that wish to use this beach. Is public space.
2) Is economically crazy. The permits to grant a new marine farm to culture fishes are scarcer than plutonium in Mediterranean just right now and one of the reasons is the contamination. The idea of culturing cheaper products like strawberries in the same place is like to bury a diamond mine under a parking. Those strawberry fields are currently destined to a very profitable culture of marine plants (Agar based companies), fishes, shellfishes, and also turism. Even if you put enough manure to having a good annual harvest of strawberries two months each year (and you are really lucky that fishermen just accept go away and don't destroy your greenway with their trawl nets) you are just losing money.
3) Is not scalable. What they are doing would be clearly illegal for any of us. If the goal is "to feed the planet", to substitute the essential proteins provided by fishes and shellfishes by a harvest of lattices or strawberries is plain wrong. Poor people need (imperatively) more proteins in their diet, not more sugar.
