You are correct in stating that marriage institutionalizes monogamy. You are correct in stating that Monogamy limits reproduction. You are incorrect in trying to draw a causal link between the two. Correlation is not causation.
Society did not institutionalize monogamy in order to limit reproduction.
They institutionalized it to control reproduction. If you institutionalize monogamy and say that having children outside of such a relationships is wrong you will limit reproduction.
You last paragraph makes no sense. The 'dominant' gender is the one who defines power, ego, and status. Hence why in the past, males are the ones who 'owned' the women, much like they owned slaves.
Why would they want to own a woman when instead they could own a man that would be much more useful.
