Yeah, I hear that. I wonder if there's a cart/horse issue here where the greatest value for low level unit tests is when you have a well-documented, thoughtfully architected system. Then the tests are verifying intentional behaviours and helping ensure the longevity of the system as designed. I don't think I have this experience first-hand, but I could certainly imagine a scenario where a well-intentioned person added a bunch of unit tests to a badly designed system, and they ultimately ended up just getting in the way and causing confusion when it was time to rethink it.
