You might find a more sophisticated version of that conventional wisdom to be less amusing and more worthy of food for thought.
It comes from Ronald Coase's theory about the natural size of companies. Companies exist at the tradeoff where the costs of transactions between multiple companies equal the internal inefficiency of a large organization. The larger the organization, the more it tends towards inefficiency. Anything that decreases transaction costs, decreases the size of organizations. And vice versa.
From that you expect large organizations of all kinds to be inefficient. Which fits your observation. Now note that government organizations tend to be are large organizations with a tendency towards complexity and no incentives for efficiency. How do you predict that will work out?
Again, whether or not this is a compelling argument is a matter of opinion. But if you want to understand the views of those who don't like government healthcare, this is a key point to keep in mind.
