Difficult to move the production of olive oil.
I don't know how much you know about olive oil, but it comes from olives, which grow on olive trees. Olive trees are famously long-lived and, together with the very specific types of land that they grow on, they represent extremely persistent and valuable investments for the people who produce olive oil.
There are a few olive trees in my neighborhood. I should plant some too. It would be fun to watch them grow.
This is not true. Next time you grab an olive oil bottle read the fine print: unless it’s very expensive it will be a blend of oils from 4-8 countries, ie production doesn’t have to be in the same country where olives grow on olive trees, as you eloquently put.
