Snarek, direct question. If NAS is as safe as it should be, why will ADSB be a benefit UNLESS that is a safety increase. In that case, shouldn't we be delaying NAS until we ALL have ADSB? I asked this question on the other page but BIK claimed he didn't want (or need) it but you have mentioned a number of times that you do.
Either the NAS system is 'safe' and therefore ADSB shouldn't even raise it's head- ever- or it isn't and something needs to be done. Your continued insistance on ADSB shows flawed logic.
