Sorry if this is a stupid question, but why does expendability increase the payload to orbit so much?

Higher structural margins overall are needed for reuse, plus:
Booster
- Grid fins for aero control
- Boostback & landing propellant tanks
- Protecting engines from entry loads
Ship
- Body flaps for aero control
- Deorbit & landing propellant tanks
- Heat shield
