I usually shoot in raw format and my Pictures directory is just a bit over 1TB. That's with about 70K photos in my Lightroom catalog--which reflects much but not all of the contents of that directory.

My total cloud backup to Backblaze is about 4TB.

That said, I generally agree. I certainly don't represent the consumer just snapping photos on their phone which probably represents "average" today.
