Why do manufactures of women's pants put pockets on them?

Pockets are so useless and they disfigure the whole deal and are awkward. It is dumb to have those pockets when we don't carry wallets and keys in them. The pockets that aren't flat, but have that inner piece of material is even worse. How much better it would be pocket-less, or with just a little sewn on pocket design. Why don't women's trouser designers wise up and cut out the nonsense ? It would sure save on alterations.
