Something that's often overlooked here is how extensive the required refurbishment is.

The "reusable" shuttle boosters and orbiter engines took substantial time (https://www.nasa.gov/centers/johnson/pdf/584723main_Wings-ch... says 4-5 months), money, and labor to get ready for the next launch. SpaceX is still making noise about trying out a same-day reflight sometime soon; it's clearly a much less involved process.
