I'd be quite happy for you to mandate transponders for all aircraft in a CTAF. Why on earth would you inflict the cost of Class E on VFR,
as well as make them fit transponders?
Your continued nit-picking, for example about "unable to power a transponder" is a red herring, as is 95% of your stuff. Keep your eye on the main game, laddie. Of course there are going to be cracks, as has been explained to you above. No system is perfect.
But anybody who thinks that mandatory radio use is silly or ineffective needs a brain transplant.
And since when has TCAS ever been considered a primary method of aircraft separation? Unless, of course, we could use ADS-B, so ATC can see them. Now there's an idea. Be careful what you wish for, LB. This is 2018, not the wild west of the 50s and 60s that Dick seems to be stuck in.
