I think you are leading yourself up the garden path Boid.
It simply doesn't make much sense to say "every surface is a photographer" , because the intentionality of the photographer is missing from a surface; "photography " (or we can substitute "painting" or "writing") is an activity undertaken, largely by humans, by people.
"just the act of pressing a shutter release" is simplisticly reductionistic (or mechanistic) ... you take photographs Boid, (I've seen them!) ... did you "just" press the shutter? ... no you didn't ... you looked, envisioned, thought, felt, acted ...
saying "everything is photography" removes the meaning from the very idea of photography ... it kills it more surely than nostalgia ever could ... you could equally say "everything is cheese" and it wouldn't be any more true (or false, come to that)
