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.
And history has borne it out: societies that adopt strong individual property rights coupled with economic freedom have delivered unprecedented wealth to their people at all levels, while societies that focus on the collective at the expense of the individual and upon outcomes instead of opportunities flounder and regress.
