I don't know about the OP's intentions, but from my point of view, having to pay or quest for anima does not mean having more anima. It's more about having to achieve something in order to have the privilege to teleport, and add some content around a useful mean of transport rather than just handing it over.

For example in XI you could trade conquest points (need to kill enemies with Signet on to earn them) for a scroll of instant warp, or pay tablets (earned by completing FOV pages) to return to your Hometown. I would not like the same way of earning them but I like the idea of having to achieve something that allows you to teleport when you really need it or are short in time and your party is waiting for you.
