I'm all for anima and teleportation. Think about situations where you just log on, and your linkshell is gathering on the other side of the world. It's pretty convenient to be able to teleport to them immediately, rather than have them wait 15 minutes or more for you to get over there.
When other methods of transportation are added, people will definitely use them. Teleports will probably be reserved for times you need to meet up with a group instantly, or if you only have a short time to play.
