Another perspective is that the Falcon9 carries about as much kerosene as a 747.

I decided to fact check you. 57,285 U.S. gallons in a fully loaded 747. Jet-A is 6.84 lb/US gal. That's about 196 tons. Looks like stage 1 of the Falcon 9 is estimated to use 239 tons of RP-1 and stage 2 49 tons.

Cool, so they're well within an order of magnitude of each other.

That's a good one, although a 747 gets its oxygen for free.

LOX is literally cheaper than dirt (8¢/lb, or 67¢/gallon).

Yes, but oxygen's pretty easy to come by it turns out.
