Regardless of the politics that modern staple crops are associated with, you still need calories. Why do you think rice was a second currency for a very long time in some parts of the world.

Also, the example of indoor farming that’s near me is absolutely running off of government money, at least for now. They got a grand to setup in an old warehouse in downtown, but also own some empty property in the neighborhood. This could be just them future proofing or it would be them looking to flip the property once the main site raises the property values.

And then there’s the MIT Food Computer, which promised a lot and delivered nothing. The smaller scale the production, the less efficient it is. If you want to feed the world’s population without a steep decline in that population, you’re going to need outdoor farming in addition to the indoor stuff.

Staple crops aren’t just your cheap empty calories. Legumes, carrots, sweet potatoes, squash, soybeans, onions, and some very healthy grains are all staple crops. Even the humble potato is fine, though many preparations of it are unhealthy. Take this soup:

• Lentils
• Carrots
• Onions
• Celery
• Potatoes
• Beans
• Vegetable broth made from the odds and ends
• Herbs & spices

Subsidies keep the farms alive in the first place. It’s simply not profitable to grow anymore. We make so much it’s too cheap to sell. Therefore the volume required and the margins are so razor thin. It’s make a profit or be bough-out by a bigger company.
