People usually bring up the GDP stuff not to criticize the fact that the US has managed to develop an national economy where most other sectors dwarf agriculture, but to pair two points: 1) California could afford to lose its agriculture sector 2) since water is increasingly scarce here, maybe the agriculture would be better done somewhere else too There's probably some counterarguments (even a 1% GDP contraction is going to hurt a bit and have some second-order effects, maybe trucking in food has its own problems, inertia in things like almond crops, I don't know), but we can probably stop short of accusing the people who bring it up of being critics of industrialization. :)
