The fact that it all depends on a massive public subsidy (both cash and water) from the rest of the state is ignored by then. They focus on arguments like "stop dumping water in the ocean" - eg make all the river run dry before reaching the coast, and "this is where food comes from" - as if it's the only place in the country you could grow food, or that other nations/regions manage to grow plenty of food in a similar climate with a fraction of the water.
