How pervasive is the use of DSC (or even VHF for that matter) on inland lakes? Is it worth the trouble of getting an MMSI? Is there likely to be anyone else on the lake using DSC to talk to?

If it makes a difference, my boat lives in the Dallas area.

Dallas? Can't you just walk to shore if it goes down on an inland lake there?
Almost. I'm not super worried about the distress features, although I can see calling for a tow boat to get one ungrounded. I'm more thinking about the other DSC features; for example I could see a group code being useful for regattas or club fleets.

My understanding is that the MMSI is "for the boat", not for a particular radio. So if your handheld was for backup use on the boat, it might make sense, but not if it's a roving handheld--particularly if it ever got used on some other boat.

Really depends on the lake. Many man-made lakes are so large that DSC is a good idea. This is also true of the Great Lakes. Lake Texoma, for instance, covers 360 km².
Sure, I can see it being valuable, and I was a bit flippant in commenting that the distress button was not important. Lots of things could go wrong other than sinking. The question is, does anyone monitoring VHF on Texoma (or Lewisville, in my case) actually have DSC configured? If I hit the red button will anyone hear it?
