If you just fly alone, with a few friends or at regular club fields then it's a non-issue.
I fully agree with your first point. The vast majority of so called interference is user error either in poor set up or most likely dumb thumb error. The fact that the 'interference' can hardly ever be reproduced after the crash speaks volumes.
The other potential fault with dsm2 is the system will sometimes (admittedly rarely) grab two channels right next to each other with the result that if there is some interference in that region of the spectrum it is very likely you'll get knocked out. FAAST and now dsmx along with FHSS and the other iteration of frequency hopping systems are far superior. Personally I use Futaba with FRsky modules and receivers, there is pretty much nothing the big players offer that frsky don't.
