Maybe some people believe women (and men) who are alive but haven’t been born yet have the right to control their bodies and not be killed, so they can exercise their autonomy one day. They would probably agree with you that “you don't leave rights up to the states. Rights are supposed to be guaranteed at all levels of government.”

Seems strange that most pro-abortion advocates would probably be in favor of tenants rights to protect them from being evicted from a rented house but are fine with a living human being lethally evicted from a womb as long as the “owner” says so.

In both cases there are two humans, both of which have rights and whose interests have to be balanced - I don’t think it’s helpful to pretend otherwise. One might also want to consider other situations where humans have decided other people are “not really” human in order to justify doing terrible things to them, including killing them. In every situation I can think of, that thinking was wrong - seems unlikely that abortion is an exception somehow.
