From this and your other responses, I think you have a pretty poor understanding of the aviation industry. That's okay— it's a weird sector, currently, because of its high barrier to entry.

I would be so happy if my plane could go 200 mph; it would make it so much more practical. It's faster than most at my airport, but not that fast by a lot. At 5000 feet you have so many more options; the regulation in 91.119 (off the top of my head, even) is 500 ft from houses + cars, or 1000 ft in "congested areas". There's some conjecture on what a congested area actually is.

Inspection do look for things like cracks, but are more for spotting illegal cupholders and ensuring logbooks are in order. There's a very keen understanding in the industry that a plane after maintenance is in its most dangerous state— plenty of folks wonder if disassembling airplanes on a yearly basis (sometimes sooner) and putting them all back together isn't worse than the alternative. On one of my plane's first annual inspections, I got the airplane back with the bottom of the engine cowling still disassembled-- parts just stuffed back in place. I then had a spark plug fail 2 hours later. We think it was dropped and cracked, but the mechanic didn't want to own up.

Unfortunately, the industry is not currently growing (you may recall some new stories about Spirit most recently). Further, most of "any other industry" are not so tied into the military and intense, stagnant regulation. People here keep telling you that aviation is in a rut. It's a rut we know how to get out of, but the government is going to have to allow us a pathway to do so. Otherwise, there are plenty of countries to look to for insights into our future— dead GA for the wealthy only, and a less free populace.
