I think ultimately PG wasn't directly criticizing those who accumulate stuff, either. As I understood it, the issue is the attachment to the stuff, particularly when it inteferes with living a good life.
I got one thing to say:
"You are not your job. You are not how much you have in the bank. You are not the contents of your wallet. You are not your khakis..."
Well, our creator is at least a type 4 civilization that is exploiting the existence of our universe to generate energy in some way. I think the ultimate purpose of humanity is to trigger the big crunch so we can exploit the infinite computational power you get from a contracting universe. Plus it would be pretty cool to be reunited with all the other matter and energy as one.
Or we're the biproduct of an axiomatic system like our mathematics.
Either way, I strongly doubt the entities superior to us, inside or outside of our universe, care about or even notice our worship. But hey, if it makes you feel better, it doesn't bother me, as long as you're not telling me who I can or can't marry or holding back fundamental scientific research.
