No. Because you stated that "no helmet equates to zero protection" which means all helmets have some protection.

O.K. I'll rephrase that. if we assume that a total lack of a helmet
equates to zero protection... :-)

Ah, but it doesn't! For years, we had a quite clever poster here (Guy
Chapman) who noted, by analogy, that his wooly cap had saved his life!

I could make the same claim. The only time I hit my head while riding
was when I was a teen. It was a fairly hard hit, and I'm sure a helmet
would have been crushed or cracked, had they existed and I had been
wearing one. So I guess it was the wooly cap that saved me.
