If Rebirth is not taken literally then why seek Enlightenment?

I've read that some Buddhists do not believe in the literality of rebirth. As someone who is new to the study of Buddhism, this is confusing to me. My understanding, which perhaps is incorrect, is that a Buddhist seeks enlightenment in order to obtain emancipation from Samsara. Yet Samsara is a cycle of rebirth, thus if rebirth is not taken literally it seems natural to then not take Samsara literally. If this is so, then what kind of emancipation is sought after in seeking enlightenment? Isn't the goal of seeking enlightenment to eliminate rebirth? What then are other reasons for seeking enlightenment apart from the emancipation from Samsara?
