You're right and wrong. You're right in that people don't know what they want. But you're wrong that industry doesn't give it to them - in this case, Dropbox did, and we (techies) said "why would you want that, you can just [X, Y, Z]?" while regular people flocked to it because it was just so much better. Sure, it didn't include direct LAN sync to begin with (it does now), but that's the kind of "perfect is the enemy of good" implementation detail that the vast majority of people couldn't care less about.
