the probable aims and suspected intentions of such a being

The general opinion around here (which I share) is that the complexity of those is much higher than you probably think it is. "Human-level" concepts like "mercy" and "adultery" and "benevolence" and "cowardice" feel simple to us, which means that e.g. saying "God is a perfectly good being" feels like a low-complexity claim; but saying exactly what they mean is incredibly complicated, if it's possible at all. Whereas, e.g., saying "electrons obey the Dirac equation" feels really complicated to us but is actually much simpler.

Of course you're at liberty to say: "No! Actually, human-level concepts really are simple, because the underlying reality of the universe is the mind of God, which entertains such concepts as easily as it does the equations of quantum physics". And maybe the relative plausibility of that position and ours ultimately depends on one's existing beliefs about gods and naturalism and so forth. I suggest that (1) the startling success of reductionist mathematics-based science in understanding, explaining and predicting the universe and (2) the total failure of teleological purpose-based thinking in the same endeavour (see e.g., the problem of evil) give good reason to prefer our position to yours.

The laws of physics would then derive from this.

That sounds really optimistic.

Note that infinite sets can have very low informational complexity-- that's why complexity isn't a slam-dunk against MUH.

Don't think of infinite entities as very large finite entities.

I'm pretty sure I wasn't thinking of infinite entities as very large finite entities, nor was I claiming that infinite sets must have infinite complexity or anything of the kind. What I was claiming high complexity for is the concept of "good", not God or "perfectly good" as opposed to "merely very good".

Wouldn't "perfectly good" be the appropriate concept here?

Yes, but the point is that the "perfectly" part (1) isn't what I'm blaming for the complexity and (2) doesn't appear to me to make the complexity go away by its presence.

I don't see how you can be sure about, when there is so much disagreement about the meaning of good. Human preferences are complex because they are idiosyncratic, but why would a deity, particularly a "philosopher's god", have idiosyncratic preferences? And an omniscient deity could easily be a 100% accurate consequentialist..the difficult part of consequentialism, having reliable knowledge of the consequences, has been granted...all you need to add to omniscience is a Good Will.

IOW, regarding both atheism and consequentialism as slam-dunks is a bit of a problem, because if you follow through the consequences of consequentialism, many of the arguments atheism unravel: a consequentialist deity is fully entitled to destroy two cities to save 10, that would be his version of a trolley problem.

It seems to me that no set of preferences that can be specified very simply without appeal to human-level concepts is going to be close enough to what we call "good" to deserve that name.

a consequentialist deity is fully entitled to destroy two cities to save 10

I entirely agree, but I don't see how this makes a substantial fraction of the arguments for atheism unravel; in particular, most thoughtful statements of the argument from evil say not "bad things happen, therefore no god" but "bad things happen without any sign that they are necessary to enable outweighing gains, therefore probably no god".

Not if the deity is omnipotent.

That's debatable, at which point it is no longer a slam dunk.
