Well, that depends on the theoretical time travel. If it were possible, would you have the power to change something and ruin the future that we already have? If so, then yes, it should probably be restricted. But if the theoretical time travel is the self-correcting kind, or if it prevents paradoxes, etc., as it does in some fictional versions of time travel, then it could be allowed. In either case, in all fictional accounts, it still needs to be regulated somehow to prevent people getting lost or people taking advantage... so, since we're already dreaming, let's add in some time cops, or even better, Time Lords. :)
