You seem to have a pretty strong but not necessarily very substantiated opinion about the topic. I really suggest you read a bit about it, if you're so inclined. E.g. Admiral Cloudberg has been mentioned in this thread, it's a very good resource of accident recaps and the impulses they give for regulations and developments. In contrary to what you're implying, "we've always done it like this" is not a principle of aviation safety. Indeed you'd be hard-pressed to find any other globally coordinated system that is so dedicated to and successful at the gargantuan task of continually improving itself, a trillion dollar industry, and regulatory bodies all over the world. A five decades long track record of drastically reducing fatalities in the face of rising passenger miles speaks for itself. To put it a bit bluntly, I'm pretty sure they don't need to be told that it would be "just as simple as (...), because that works for an elevator".
