No, I don't think you are making too big a deal of this.
Just a few points.
1. Yes, originally people dove, flew airplanes and drove cars all without certification. But after many accidents we evolved and made certification/license the requirement. Los Angles County in California passed a law requireing certification in response to the number of dive accidents. I will also point out that back then you did not have SPG and did not know nearly what we do today about diving and cigeretts did not cause cancer. We know more now than then and certification is just smart. Yes accidents still occur but at least you have a fighting chance of not doing something stupid because you did not know.
2. Is the "tech diver" a dive insturctor? If so then he is probably doing a discover scuba. If not, he should not be doing what he is doing
3. Dawin cleans the gene pool from time to time.
