Capitalism (strictly defined as the private ownership of the means of production) can’t exist without the premise of private property being protected by laws that are collectively agreed upon, enforced, and adjudicated by peers within your community.
This implies that any capitalist society is compatible with democracy, as in, “the will of the masses controls society” and not as in “you get to vote for genocidal liberal who will make us richer, or genocidal fascist who will make us richer”
