There would be 2 purposes to owning an entire planet of females:
> Profit
An entire planet's population of females means an entire planet of laborers and workers, producing whatever I want, be it for reselling or for my own personal consumption.
A lavish palace? Beautiful works of arts? Personal orchestras? All for myself.

> Variety
With an entire planet's worth of females comes the endless differences between them, and how a Man can use them.
A Man can play the Savior to a slum rat, or humiliate the noblest of ladies. He can enjoy talents of all musical instruments. Whatever physical preference he desires, there's bound to be one on the planet. Finish torturing one to the breaking point, and he can just grab another on the street.
From a countless number of fillers and trash, a Man can assemble for himself the ultimate harem, then just as easily discard them all for another.
