Not a mockery it just doesn't qualify under the LSA rules.

Then may I suggest those rules are too restrictive? Why have an upper
speed limit when you are already limited on power?

There's no limit on power; merely a limit on maximum cruise speed. The FAA
views LSA as simple, low performance aircraft intended for recreation. "The
FAA believes that a maximum speed limit is appropriate for aircraft designed for
operation by persons with the minimum training and experience of a sport pilot."

I can't help wonder if one purpose of that legislation is to protect
established, but inferior, designs.

Name one "established" ready-to-fly aircraft, built in the USA, that met the
current LSA standards prior to their implementation. Or are you claiming that
Cessna lobbied to protect the resale value of the Cessna 120?
