> Every report on Falcon 9 costs has made this mistake forever. SpaceX does not release their full costs. Not really relevant. The correct metric to make the comparison on is the fully amortized cost to the government per launch. The government doesn't pay for SpaceX's facilities or development - all of those costs are rolled into the launch price. But that's not true of SLS.
It is not possible to do a fair comparison of launch costs between Falcon 9 and other platforms without knowing the true cost of Falcon 9 launches.
I don't know why you're so obsessed with cost. The only thing that matters when it comes to commercial providers is price. And SpaceX, (as far as I can tell) stands alone among the medium-heavy lift providers by providing a price directly on their website.
Of course, for government launches the government typically wants extra services, which does boost the prices different levels for different missions (I think the Europa Clipper mission is particularly expensive for example). But all of those missions are competitively bid, and SpaceX tends to be the low price bidder, so those extra fees seem like they're probably pretty reasonable.
