For well over 90% of divers, SCUBA just isn't the big, complicated, dangerous activity that the industry has made it out to be.
I'm not sure what that has to do with the business of equipment manufacturing for the scuba industry. Business is business and its a risk/reward model, and manufacturers and entrepreneurs deserve a generous profit for the risks they take. If you aren't willing to reward companies for their risks there is little reason for them to be in business, instead they could come work where you work and just draw a guaranteed pay check.
The scuba world you're referring to is similar to the way people had to live in the Soviet Union with 1 state run business that produced low quality items that were unreliable but cheap, with a choice of variety of black, ebony or charcoal. As soon as those people had access to the west and all the high-quality manufactured goods, they rejoiced and abandoned the soviet crap for high quality western goods. I don't see anybody going back crying that they can't find a cheap low quality soviet refrigerator, that broke down every 2 months.
I have regs that go for years without needing service. If I paid $100 for a reg and it lasted for 3 or 4 years, and the company folded, it's not such a huge problem.
Broken reg? Take it apart and fix it.
Can't get parts? Toss it in the recycling bin, spend another $100 and get a new one.
You seem to be fixated on a $100 regulator. A regulator is just a tiny fraction of the millions of dollars of scuba equipment. I suppose you'd be fine with a garage manufactured camera housing that works for awhile and then leaks and destroys your expensive camera, you'd just slap some silicone caulk in the plate separation or just throw it away and buy another $69.00 one and another camera? Or in your world, there would only be one camera to choose from and one housing and eventually no housings as everyone stopped making them since there was no money to be made anymore.
The cheap item that lasts for 3 or 4 years is the pipe dream not the reality. The reality is the cheap item lasts for 3 months. Or it breaks while you're in Truk or on a live-aboard and your diving is over for the week and you light all the money you spent getting there on fire and just shrug your shoulders and say "well at least it only cost fifty bucks and it lasted 3 years."
The idea of cheap and throw it away and buy a new one really never works when those items are paired with far flung locations that are expensive to get to. Of course the answer I suppose would be to just buy 4 of everything and pack 10 suit cases full of gear to go on a dive trip, unfortunately there wouldn't be 4 of the same thing to buy, and if you did spend a year accumulating 4 of them, none of them would be interchangeable, you'd be cursing as you tried to swap out a part that frustratingly every one of them is slightly a different size, not off by much, but just enough so it wouldn't work.
Or I'd take the reality we really live in today much better and having the ability to pick and choose from multiple sources, items at different price points, quality levels and features to manage participating in a sport that is equipment intensive.

The point is that the gear necessary for 90% of recreational divers does not need to be complex or difficult to manufacture and does not require R&D or "innovation"
And how do you think some of this equipment that today is not complex or difficult to manufacture went from being very complex, large bulky, unreliable and difficult to manufacture to the simplicity and reliability you enjoy today?
You think that happened because people got it there working on it in their garages or that it evolved over time through there being enough of a market for businesses to perfect it all over time and years while making enough of a profit to spend money on research and development?
