Will female guppies be better off without male guppies?

Guppies are live-bearers. Male guppies want nothing more than impregnate the females.

They will chase after the female guppies 24/7 nonstop. It will be quite stressful for the female guppies as a direct result of always being chased after. Then the female guppies will become pregnant and give birth to guppy fry every now and then. You will have an overpopulated tank in no time. Constant pregnancy and give birth also shortens the life span of the female guppies.

Since guppies aren't even a school fish species, they do not require to be in a group. The female guppies will be happier without any male around. Although if it is up to me, I will get only males because they are better looking. Please do not call me a sexist.
