I have found over the years people are going to do what they want to do. All you can to is give the tools to make the right decisions and move on.
During the winter in SoCal, I regularly ask people trekking poles and/or Microspike on high angle icy slopes how are they going to arrest a fall. The response is a uniform...I AM NOT GOING TO FALL!
This attitude is prevalent on MMWT and like the winter in SoCal people rarely get hurt doing stupid things. However, when the do it is on the 11 PM news.
Back in 2006, there were signs on the patio cover and at the wilderness line, "PEOPLE DIE HERE" in big red letters. Those signs were taken down, in my mind, because they did not fit the Chamber of Commerce narrative of everything is going to be ok. Don't worry, be happy.
You can put all the signs up you want and they will be ignored...unfortunately.
