I'm actually wondering if SE actually is considering eventually restoring anima use for teleporting some day down the track, given the fact that the aetheryte guards explicitly mention it even though it no longer serves a gameplay function like it did in 1.0.

Maybe eventually there could be some event in the future where the aetheryte restoration debt the three nations have is finally considered paid off and an option is given to adventurers from then on to use anima or gil to teleport, with the gil cost increased to compensate. Or maybe I'm just flapping my gums here.
