He's upset that the government is (seemingly) incompetent. Defending their incompetence does not change the fact that they were incompetent as someone was so easily able to propose a solution while we have little reason to believe the government had a plan. It doesn't matter if that someone is the world's foremost expert (he's not, by the way) - what good is the government if they can't solve problems they're in charge of fixing?

I would be sympathetic to that if this fix was something highly complicated or requiring significant expertise to come up with. Then I could understand this oversight. And perhaps that's the case here, and it's just my ignorance speaking, but "relax stifling zoning restrictions to immediately double capacity" doesn't seem like it fits into that category of things.
