Algae needs solar light, so you will have to flood a lot of land to get enough.
Also, in case of a war or blockade you can switch the corn use from etanol to food. You will have to eat tortilla and polenta for a year [1] but it's better than algae from seawater or famine.
Here we use sugar cane to produce etanol, it's more efficient because it's a C4 plant. I guess it's possible in the south of the US.
[1] It's not so bad in my opinion if you can mix some meat in the sauce.
