I initially thought the same, but it depends on what you will return to. Assuming you are talking about PvE CLogging, it could be that you are returned to an instance that contains the same scenario as you left eg a bunch of cops waiting for you.
You may be right though, if players CLog to avoid the rozzers & return to an empty instance (as they currently would) it won't be much of a deterrent.
For PvP CLogging I don't think there would be a net change in behaviour either way, but there are solutions available.
