Agreed. I was going to say something to the tune of "Yes, I think it should be allowed, but most women (myself included) don't want to be outside topless and thus it would be rare sight even if it were legal." But I quite like the idea of it being illegal for both women and men to be topless in public.
I mean, yeah. I've seen some guys who were lookin' pretty indecent without their shirts on and no one bats an eye, but as soon as a woman pops a breast out to feed her child people are falling all over themselves because they're too busy watching her rather than where they're going.
