Simple distinction of capitalism vs socialism is private vs socialized profits. Where the commons are a social asset, profiting off it gives society a return in exchange for diminishment of commons.

Tradgedy of the commons is usually a glib argument ending remark made when you point out the theft of the commons taking place, or the privatising of profits with socialized losses. Its meant to uphold theft as a feature of democratic capital supremacy.
