And that's because the airships cost money. From what I have seen lately, DDO is all about the store now.(not neccesarily bad) So, while I have agreed with the OP's and many others request to change the way teleport works, it will probably never happen.
Unless, you make a modification.(don't kill me for giving them ideas)
How about start you off with a the current locations.
Then allow the caster to "buy" extra locations from the store. Now how those extra locations are used, I like all the above ideas, mainly allow us to set the bind point where we are standing.
