Haven't had any problems with a Basic Service myself so I'm a bit surprised at some of the comments here. Around my local haunt ATC lets me know that there is traffic in my X o'clock at Y miles and Z altitude, I look, see and avoid, whether squawking or not, job done and no hassle, just like in ye olde days of FIS.
Fair enough if you don't think you need to talk to anyone, but there's no harm done in letting others know where you are and knowing where others are.
