This is one of the worst lawn advise postings I think I've ever seen.

Then why did you full-quote most of it?

And why did you not quote the last part pertaining to tree diseases
propagating from leaf litter? Are you also claiming that that was
innacurate, false or fabricated information?

It's a fact that municipal gov'ts do not want to see cut grass taking up
valuble space in landfills so they invent new propaganda that leaving
clippings on the lawn is better for your lawn.

It's a fact that you will need to mow more frequently if you don't bag
your grass.

It's a fact that you will need to pay more attention to thatch and that
grass cuttings will promote thatch buildup if you don't bag your grass.

It's a fact that grass clippings WILL NOT provide most of the nutrients
required by a healthy lawn, and at best will provide only 25% of the
required nutrients and that commercial fertilizer applications will be
necessary anyways.

It's a fact that the thicker the lawn, the more problematic it is to
leave the grass clippings on the lawn. This becomes important as people
resort to over-seeding as a method of weed control vs using herbicides.
