Capitalism is a very specific model of property rights and economic freedom as far as consistent with that model, which was designed—incrementally, over a long time—to advance the power interests of a particular clases (mostly not collectively, but as the aggregate of individuals in that class leveraging their growing power to advance their personal interests.)
Confusing it with “property rights and economic freedom” more generally is just as wrong as doing the same with feudalism, which likewise featured a particular model of property rights and economic freedom so far as consistent with that model of property rights.
