Burlington Bill. Seems to me model railroading in general and O scale in particular plays out something like the old Barnum and Bailey 3 ring circus. Lots of different types of acts in the rings and all around the sides all doing their thing appealing to a variety of interests. Like the circus there's something enjoyable for everyone no matter which scale and number of tracks. So why not just sit back and enjoy the variety various modelers bring your way? Huh?
I think you're totally wrong above on the relative reliability between 3RS and 0 scale 2 rail. Until 2012 I was a 3 rail scale guy using Atlas O 3 rail track and Lionel Legacy, TMCC and MTH DCS. In 2012 re-using only the benchwork sub structure I completely re-did my layout and switched to 2 rail 0 scale using Atlas O 2 rail track and a major brand DCS system. Five years later I can objectively say that both both layouts were/are equally reliable in all categories. I feel compelled to say your wrong because I think there are a lot of guys out there who would really like to switch to 0 scale 2 rail but they hear guys like you and it discourages them from switching. I never looked back and am really happy. I still greatly enjoy my friends' 3RS layouts and greatly admire their modelling abilities and they seem to enjoy mine. Same for our HO buddies. It's all good -- like the circus.
