I agree with you
As I said, there are various reasons why a bigger sensor can have advantages. Just not the reasons given in the original post in this thread.
Edit:
I'd like to add a general comment about why I personally object to equivalence so strongly. It's because it's overly reductive. There are all kinds of complicated factors that affect the quality that we'll get from a digital camera, and the physical sensor size can indeed be one of those factors, but never in isolation. Equivalentists try to reduce all the complications down to a simplistic explanation, and in order to do that they distort reality to the point where their explanation loses most of its connection to the actual facts.
Sometimes it's better to just accept that something is actually really, really complicated. Then we can also accept that we don't have to worry about most of those complications when we're taking actual photos.
Over and out.
