If the point of shooting is turning money into noise, as it is for many Americans, then suppressors don't make any sense.
If your firearm is a tool to be used for a job, then they are a natural accessory that improve it in many ways.
Suppressors have their use, but I view it a lot like night vision in the idea that it's something that conceptually sounds like a real game changer, but in reality isn't nearly as valuable or approachable as it sounds unless you have the time, patience, and resources to make it work. For the average Joe, just wanting a gun in case some melanated gentlemen break in to get reparations from his wife and daughter, suppressors do not justify the cost or effort.
If you wanted one "work" gun that you decided from the outset would be ran suppressed, then I think you could head off a lot of the issues, but really only if you already knew a lot to begin with. Even then, it would need to be some really specific "work" to justify only running subsonic ammunition and robbing yourself of performance, as any supersonic ammunition would still give you the gift of "EEEEEEEEEEEE", telegraph your location, and scare the fuck out of any bystanders in ear shot.
You can't repair them, you have to report whenever you go out of state with it, you have to report if you change residences and if it turns out to be complete shit, which is a non-zero chance with all the crap cans on the market, you're stuck with it or have to destroy it and report doing so.
I have a lot more issues with suppressors than just the ones I listed, I was just trying to stay in context to the initial comment. In addition to what you said, I have also observed a lot of practicality problems. The suppressor works fine, but the sights aren't high enough so you can't see and need to get new sights or a riser. The suppressor works fine, but it stings your face with high velocity grit every time, or its choking you out with leaded gun smoke every shot. The suppressor doesn't work fine, and it turns out you need a special adapter, or a new buffer pad, or a different recoil spring before it will function properly. Or best yet, there's nothing wrong with the suppressor or the gun, but it turns out the suppressor is just a cunt hair too heavy for the gun to cycle reliably with subsonic ammunition, so you need a whole new suppressor if you want to run that gun suppressed.
Yeah, most of these problems can be solved by more time and money, but after more than a few range trips where we had to pull the suppressor off of the gun to get it to run, I just don't see the point of one unless they are dirt cheap and the legal restrictions are removed. Any money that I would put towards a suppressor, I would much rather put towards anything else firearms related, as it currently stands.
