California produced 1.94 million gallons of olive oil in 2023. That same year the US used ~98.5 million gallons of olive oil. There just isn't enough space to produce that much olive oil in CA much less produce it profitably or in ways that wouldn't devastate the environment. And all that is ignoring that it takes around 10 years for an olive tree to get to consistent production.
Oh, I agree. I was just pointing out we have some, and it's going to get a lot more expensive now.
