This essentially negates the benefits provided by non-destructive editing.

I've seen other people do this in post-processing tutorials, but I'm afraid I do not understand why.

I preserve all of my layers so that I can individually make enhancements to specific types of adjustments, and also so that I can see in the future what types of changes I made to a particular image or series of images.
i wondered this myself ?
