This is true, the symptoms the article is looking at are strong signals of non-free-market policies. Under capitalism, the failure mode is going to be very high prices. If the failure mode isn't high prices then the market probably isn't being run as a free market.
Like when there is a crisis and the government steps in to ration or fix prices and a breadline forms - that breadline isn't a capitalist problem! Capitalism was suspended because the government didn't like what would happen under capitalism (which, I think we all agree, would have been high prices to the point where there was still bread on the shelf that people could buy). The capitalist outcome isn't a utopia, and isn't even pleasant, but it also isn't a breadline.
