> not believing in gravity That metaphor holds if he doesn't believe that the US government has ever obliged a business to do anything; it's objectively true that the USG exists and asserts power over many businesses. But "believe in" there is pretty obviously a claim about desirability, and I think a lot of people don't believe gravity has intrinsic moral value. Actually, I like this metaphor. Gravity isn't intrinsically moral, but from a human perspective there are certainly right and wrong values. Deimos, where you can accidentally jump into orbit, has too little. Jupiter, where hydrogen is crushed into a metal, has too much. So now we're back to quibbling over the desirable amount of an amoral force, and comparisons to physics haven't changed the situation.
