Aren't those two reasons sufficient? No others that I know of.

Is this a common concern among sailplane pilots? I'm just trying to
understand the thought process behind someone wanting to fly
"anonomously" with a Mode S transponder. I don't think sailplanes
would be much good for smuggling or terrorism. The only reasonable
intent I can think of is that people don't want to be identified when
wandering into airspace they shouldn't be in. What am I missing?

If you wander into airspace you shouldn't be in, broadcasting your
position with Mode C, would you be left alone? In R or P airspace, I'm
pretty sure someone comes looking for you, but how about A, B, C, and D?
