So, I was driving around town (Central NC), and saw a bunch of people

No. This can create a perfect environment for fungus, mold,
destructive insects and rodents. The bark of a tree should not be
covered up with leaves or mulch, but I see this done all the time.
Like people, some trees can take more abuse than others.
