For one minute,which you would know by now if you've taken the rescue course properly.
The diving world is much, much larger than "the 50 states," most of it in the far more reasonable parts of the globe where people understand helping others is a desirable thing to do. If you think something is a bad idea for those in your situation, then stop there. What's the point of making sure the rest of the world follows your silly paranoia that has nothing to do with our contexts?
I'm sorry if my words seem harsh, but you strike me as someone who takes his argument from a tiny grain of sand and insist the entire ocean floor must be exactly the same, without ever being in the water. You went on a multi page rant about how disabled divers shouldn't be trusted to rescue others, while you yourself doesn't have any clue what disabilities mean and what our diverse lived experiences are like. I'd suggest you take a step back and contemplate on the vastness of the universe. Remember how little we know about it all, and sit humbly in your opinions.
Disabilities are not defections. Lawsuits are mostly a US thing. Let's get over it.
