'We're only defending the imaginary ideal!'

That's not how words work. Things mean what they are used to mean.

Y'all understand this perfectly when describing "capitalism." That word becomes synecdoche for every level and aspect of modern reality. By definition, capitalism is only really the part where having money makes money, but nobody has any trouble understanding what you mean when you refer to its consequences and implications. Nor would you respect if libertarians split hairs about "corporatism." Like oh, this isn't capitalism, because it lacks X and Y and Z, which have never existed, so how dare you talk about bad things that actually happened.
