A valuable part of the ADS-B out mandate is that planes even as small as mine (a.k.a. tiny) can cheaply (<200$US) pick up ADS-B in and display it on a consumer tablet. My private airplanes now have pseudo radar. Not every airplane in the air is broadcasting, but most are. This is a huge safety win. Almost without exception I'll see airplanes on my tablet long before I have visual on them.

Without ADS-B out on your airplane (which you don't have for <$200), you will only pick up mode-C traffic in your area if there's another airplane nearby with ADS-B out and coded to receive ADS-B in. You would then be intercepting/"piggybacking" the traffic transmissions meant for that airplane.

Fortunately (unpopular opinion among pilots) the FAA is slowly phasing in ADS-B out as required equipment. Starting Jan 1 of this year, you need to tx ADS-B if you're anywhere you'd otherwise need a Mode-C transponder, including around many airports.
