My quick "reality check" question is this? If he had a o2 hit, stroke, heart attack, while in the beginnning stages if deco on said dive..............do you know enough about rb's and how to properly deco while assisting with said emergency? You may and I am not taking a personal shot, just throwing a point of view out. You did say you went from hour dives to hour deco. Trust me dives have hurt and killed more than a few people. You may already know these things, you just did not make it clear and that, to me, is why most training is necessary.
I have dived with several guys who started in the 60's and 70's who finally got certified to get tanks filled. These guys also learned in a different day and time when more was expected. There are definitely too many "cash cow" courses, drysuit being one. To have these courses as an option is good as we all learn in different ways. OW, Rescue, any overhead, Rebreather, etc are good "taught" courses because we don't learn some things on our own. Back in those days people dived with a single tank, no deco, etc. The tank would run out, for most, before deco was close. We have gone way beyond that now.
In the society we have become, this is more than a piece of paper. Liability, carrying hazmat (yeah 02 and portable high pressure cylinders, over 300 psi according to training I have taken yearly, due to their explosive possibilities) and other such things have made this necessary.
I am not an instructor, DM (at least for many years) or a dive shop owner. On the other hand I believe in structured training mostly and mentoring on the rest. Like I said, "dive society" has gone way beyond single tank no deco diving. In theory, I agree with your point but to me it is not that simple anymore. FWIW
