Busy Beaver numbers are extremely uncomputable, so some agents, by pure chance, may be capable of acquiring much greater utility than others.

Pure chance is one path, divine favor is another. Though I suppose to the extent divine favor depends on one's policy bits of omega begotten of divine favor would show up as a computably-anticipatable consequence, even if omega isn't itself computable. Still, a heuristic you didn't mention: ask God what policy He would adopt in your place.
