> If we accept your argument that Google can't measure the speed of a webpage

Correction: Google can't predict the speed of a random webpage to a random user around the world.

But you can reasonably predict that pages hosted at widely available CDNs around the world will load faster on average than pages not available.

Google _can_ predict the speed of any webpage to any user. Google Analytics data is enough. Your whole thread is predicated on Google having that one product (crawler). They have everything.
