I've been on both sides of this since I've dived off charters been an instructor and shop owner (hey Rick...cavern, wreck and ice...LOL) and if a business owner decides a situation represents a risk that he is unable to accept I understand even if I may not agree. It's his livelyhood and his decision.
At the same time the poor quality of some training has devalued the "card" and there's a card for everything. Some seem to want those cards to become licenses which they're not at the moment.
Sooner or later a diver has to rely on their own judgment no matter how many cards they have. I have a cave card but there are some cave dives that I choose not to do...the same with wrecks. I most likely have the cards but that doesn't mean that I'm up to a given dive and no one but me is in a position to make that decision (since I have the cards)...and the cards don't help.
Once you get far enough along the learing curve you find out that when it's not fun it's not safe and cards have little bearing on it. A boat owner needs to do what he thinks is best and I'll do what I think is best...on his boat or on another.
In fact all the easy to get cards might even be part of what gets divers so eager to go out and do dives that they really aren't going to enjoy and maybe not even survive.
