Walking around with a photo versus walking around with a hundred million photos and asking everyone simultaneously should not be considered about the basic same thing.
Like, is a victim of life threatening domestic violence who shoots their abuser during an attack a "murderer"? Or is an abuser who killed their spouse in a rage a "murderer"? Obviously these are different and the prosecution/defense hash that out over a very, very long time.
Details matter. Ask any public defender.
Note that we're talking about murder because the comment that set this off tried to pass off "throwing spears" as benign comparatively. No it isn't!
The spectrum stuff is about the likelihood of harm was my interpretation. Obviously we shouldn't be throwing spears, but there's probabilistic side of it that doesn't exist with nukes, and there's a spectrum between all of that with various probabilities of extents of harm. So if the harms of using these technologies intrinsically carries similar probabilistic risks (false arrests, elevated charges, etc), why not treat it as a risky object worthy of kicking someone off the range? I'm reminded of situations of waiting for the rangemaster to walk away so you can do something stupid and risky.
