Okay, that pretty much encapsulates the difference, then. This has helped a lot!

But I don't see how you justify distinguishing configuration-based phenomena from other ones--why should there be any electrons, any gravity, any spatial extent, any distinction of any type whatsoever, except thinking makes it so?

Or are you saying that, too? There is no anything except thinking makes it so? There are no independent microscopic properties to synthesize anything out of. It's not emergence that is the problem. It's anything at all that is the problem. The solution: all thought, all the way down. Berkeley would approve.
