If people didn't feel the need to specify "trans" men and women as being something distinct from other men and women in general day to day life, we wouldn't necessarily need the word "cis" as a contrastive. We don't live in that world. The alternative here is to simply call trans women "women", and trans men "men" without any sort of special markers or identifiers, ever.
But of course, even then, when when talking about trans issues we still kinda need a term for "not trans". Cis- is the well-established prefix opposite of trans- and is very clearly the best candidate. pitching a fit over the mere existence and usage of the contrastive prefix in discussions of trans issues is very, very silly.
