Indeed the Falcon 9 propellant cost comes in at about $40/lb of payload with
expensive RP. Commercial airlines do about 50% of their costs as fuel.

But if you are still fixated on SSTO, then... I guess there's no hope
for you. Even with a Sabre engine, which is just about perfect for a WWJ
TSTO booster..
SSTO, TSTO, witches on brooms, I don't care. I am focused on low cost
and don't care how it is done. I actually started with looking into a
space elevator proposal to get (step) taper out of a constant diameter
cable, and tried hard to get Kevin Parkins microwave heater to orbit
scaled up to where it could support a power satellite project.
If anyone has another proposal that will get the cost down below
$100/kg to LEO, I would sure like the read the proposal.
