These recommendations are a good idea, and probably what nearly every AFF instructor out there already steers their students towards. Putting them in the SIM will unlikely change much. Making them a rule will also do little to change the current situation. Rules only apply to those who follow them.
If these people with bad attitudes don't listen to you now (giving the same advice) what makes you think they will listen to your rules or recommendations just because the are written in a book published by USPA.
The simple fact is people are going to get hurt and die flying parachutes, and no matter what we do, the faster these parachutes get, the more people get will hurt and or die. I think you intentions are good, but the approach is flawed. There is no rule or regulation that can legislate good judgment. Why do we insist on protecting people from themselves?
To prevent these accidents, the culture of skydiving needs to change not just a set of rules. Swooping small fast canopies is cool, and many people are not willing to take the time to develop the skill required, they think they are different. Peer pressure is the most effective weapon against this type of problem.
I accept that there are a certain number of "egos" out there that I will not be able to teach/help and I just move on to the ones that will listen. There is no reaching some people. (This is where a good S&TA should step in not a BSR) The best approach I know of is to offer help to those in need of it; if it is refused, ostracize those that conduct themselves in an unsafe manner. Eventually they will tire of solo jumps and either shape-up or ship out.
The skydiving community will never unanimously accept criteria for wing loading; we are all very independent people, many of which skydive as some form of rebellion. All a set of wing loading rules will do is give them new thing to rebel against.
For those who want to learn to fly parachutes safely there is a wealth of knowledge out there (internet/DZ's/canopy schools.). The same people that would follow the rules/guidelines are likely the ones who would have sought instruction anyway.
I think your heart is in the right place but your time would be better spent befriending one or two of the people you see as "at risk" and teaching them, rather than proposing legislation. This type of change cannot be imposed on a group by rules, but instead must emerge as a movement from within!
