When I was a kid the Shuttle was going to launch every week, but that turned out to be impossible given the amount of rework it required, the most flights it did in a year were 9, and it averaged around 4.5.

Forget the 24 hour turnaround. If SpaceX gets to the point where they have weekly launches it will be utterly delightful and amazing. Essentially to do that they have to not only make re-use work well, but also have to pass cost savings to customers to increase demand.
