Other than the decent system ruining our future, because a preventable catastrophe has been left to unfold because of corporate greed, the analogy is senseless from a pure logical sense. Of course you aren't just gonna pick the cheapest option when deciding to plan a tunnel or a bridge, you go with the option that makes the most sense. The information problem is of course more about how we knoe the desires to be fulfilled, but even there, don't you think, that most desires, that capitalism fullfills are nothing more but artificial. Nodoby would desire a bigger car, if a bigger car would not exist. And while it is true that former socialist countries had that problem, of not meeting peoples desires, new forms of socialism could utalize the internet to have a democratic edge on that for example. I would highly recommend you, to step out of your neoliberal bubble, and read Thomas Piketty's "A quick history of equality", and look up PlasticPills on Youtube, he has some really interresting videos on how capitalism forges us.
