Muslim Women's condition

During the khilafah of Umer Farooq(ra) there used to be bare breasted women walking around in Makkah, he didn't punish any of them.

And as for punishing your own wife or daughter doesn't mean you torture them or kill them.

Prophet Muhammad(SAW) in his life never struck a woman, a child or a slave. So how can you justify that men can actually beat women for not covering up?
