Besides which, by bothering to try to come up with a wholly naturalistic worldview that never resorts to mysticism in the first place, Eliezer is massively ahead of the overwhelming majority of, for example, laypeople and philosophers.

That means that if I just say "space aliens have replaced the President", I'm saying something bad, but if I copy a math textbook, and add a footnote "also, space aliens have replaced the President", I'm saying something good, because the sum total of what I am saying (a lot of good math + one bad thing about aliens) is good. In one sense that's correct; people could certainly learn lots of math from my footnoted math textbook. But we don't generally add these kinds of things together.
