I'm not sure what safety features you could be referring to. And people reporting lost guns has nothing to do with manufacturing. And I don't know what purpose it would serve to report lost guns. I do know that law enforcement takes a special interest in stolen guns. But I doubt that being aware that something is stolen, like a gun, will some how prevent gun crimes.
In our society, if someone is making something that doesn't work properly, people will not buy it, and they will either improve their product or go out of business. We don't need the government to be involved, the market will fix that.
You have never explained how someone owning a gun makes them less safe.
