Then we must also shut down the helmet companies. As Jerry Seinfeld said (paraphrasing once again), "the only purpose of the helmet is to protect a brain that is functioning so poorly as to put itself into a situation so dangerous that it required the use of the helmet".
So, using your logic, we should immediately close down all helmet companies. After all, giving somebody a helmet may give them a false sense of invincibility. To say that the "helmet protects your brain from damage" may actually be telling them that it's a good idea to go out and bang their head off of a wall at 100 mph. I mean, hey, they've got the helmet. Why not?
Regardless of whether or not you teach them to perform the activity safely. Regardless of whose fault it would be were they to make that choice, we simply can't trust them to make that judgment call.
Some would say that having an airplane with the capabilities of a Pitts gives one the ability to get themselves into trouble. I assume that nobody has ever gone out and pushed their Pitts outside of its flight envelope? Making an airplane that can do that is simply dangerous. If that could happen, perhaps we shouldn't be selling those either. After all, somebody may make a poor decision after listening to a Pitts salesman. We simply can't allow that to happen.
So, please explain to me how allowing somebody to buy a FIKI Cirrus and allowing somebody to buy a Pitts is any different? Couldn't the stupid rich guy get himself into trouble with either if they were to use them improperly? It's all about the decision making.
