Artifical only doesn't include prepared baits. In fact, in several states, you can't use organic smells like shrimp oil on your fly or lure since it's based on a bait by-prouduct. I don't see how you can stop people from still fishing - if someone wants to toss a fly on a lake and let is sit for hours that seems like their perogative.

If your game warden hasn't answered the question perhaps you should get a hold of someone at the division of wildlife who defines the regulations. Then have them talk to your game warden so the story gets set straight. People shouldn't be fishing power bait of any kind in artificial-only water, it defeats the purpose of the original intention of the regulations.
