Market failure is a term in the modern economics profession
Basically you dream up some impossible situation, call it perfect, denounce the market for failure to match your perfect model, and finally call for violent intervention to fix the alleged failure without assessing whether or not the violent intervention might also be subject to failures
A common example is the alleged under-provision of "public" goods
Eg you can't defend Cincinnati from nuclear weapons while excluding the home of some random guy, so he would prefer not to pay nuclear defense taxes since he would get defended anyway, therefore you are entitled to create a monopolistic nuclear defense agency that uses violent force to compel this random guy to part with his cash
