The only way you could enforce this ban is for park rangers to have snowmobiles to patrol the park. Does that make sense?
It's not really that hard, and a few forays by individuals aren't really a problem. The snowmobile tours are controlled by contractors, and they enter the park at the gates (just like cars). So they'd really just have to watch the entrances.
