Transponders make radar much easier. No need for active radar

no need for active radar. just have your guys at base watch your flight path and route you safely. this way you can deactivate your transponder and still be not of danger to anyone around you. I’d imagine this is how they to it

Then you have to rely on a human element, which is a horrible idea in a rapidly changing environment.

Imagine someone hits the base and takes out its comms. You no longer have any idea where anyone is.

Every airport with radar has active radar, so they're going to "see" you anyway even if the people hoovering up ADS-B info don't.

And yes, there are people who have cameras pointed at the sky all over the country, and with software that says "I see a plane, and I don't see no ADS-B".
