Guild/LS Banks have been a scam since before FFXI was created, and their being stolen or embezzled from is nothing new. It's pretty much why they exist in the first place. This is a player problem, not an SE problem.
Personally I don't care for name changes either, but the name can still remain bound to the same player ID. Many things in life have the potential for abuse and misuse, but are generally beneficial. Just because someone could take advantage of something doesn't mean that something shouldn't exist if it will make a lot of other people happier more productive or whatever.
