I understand your concerns but personally have a specific reason for wanting them - testing the PAW installation and setup. If we have known base stations at locations and airfields and we are on the ground or flying overhead - to and from etc - I can see the detection and if I being obscured from the front, side etc due to placement.
I know it won't be perfect but at the moment I don't see any way of testing the setup and other than assuming it is working. With known locations you would be raising an eyebrow should they not appear in SkyDemon, PAW etc.
I can see how testing could be useful, but until we have a way of selectively ignoring base stations, I think inconveniencing the many for the sake of the few is the wrong way to go. I tested mine in a mutual test session with another PAW user at my field. We did 10 minutes on the ground, then went airborne. That's a lot different to having it bleating for 10 hours a day on the basis that someone might want to do some testing sometime.
I don't want to appear overly aggressive about this, but equally the idea that we start deploying PAWs to help us navigate is also just nonsense (you haven't said it, but one or two others have). It's an avoidance device, not a homing device. By definition we all have much better means of navigation right there on our traffic displays!
