The system looks pretty damn robust given that we've just shut the global economy down and the food still keeps coming in. Maybe with some hiccups but that's complaining at a high level.

The reason decentralization doesn't make a lot of sense is because we need to produce food cheap and at scale to feed the world. Putting thousands of dollars into vertical farming equipment that doesn't fit into the apartments of most people on the planet is kind of silly.

There's also simply division of labour at work here. It's uneconomical for large portions of the population to spend their time farming.

It's essentially just a recreational hobby for wealthy people or maybe reasonable on a Mars Colony, but here it does not make much sense.
