Yes, I fully understand the reason for tracking: profit maximization. Isn't it interesting, though, that enormous swaths of the advertising world manage to be profitable without engaging in tracking (because it's not possible, but that's beside the point)?

Sure, that's a reasonable view. It's certainly Mozilla's. My view, though, is that it instantly transforms the browser away from being a "user agent". It means that instead of an ad company tracking me, my browser is, which means that the browser itself has become an agent for others rather than for me.

It's just moving the tracking out of the hands of ad companies directly and into the browser. You could argue that's better, but it's still tracking me. It puts the browser into a position where it is adversarial.

That, at heart, is why I will be sure this stays disabled. To do otherwise means that I can't really trust the browser and will make the web even smaller for me than it has already become.
