Bill, you are just plain wrong about all this.

It was fairly simple to reconfigure the Saturn V to launch Skylab to low Earth orbit.

"Skylab was America's first manned space station. It was built from the S-IVB stage of a Saturn V Moon rocket, its hydrogen tank being converted at the factory into spacious two-storey accommondation for a three-man crew. The bottom section contained a ward room, sleep compartments and a zero-g washroom/toilet; above was the spacious workshop. The total internal volume of Skylab with Apollo Command and Service modules docked was about 368 m^3 - approximately the same as a small two-bedroom house."

About three launches of a Saturn V in the "Skylab configuration" (each 368 m^3) would have built the international space station (935 m^3).

HOWEVER, "To construct the international space station, more than 100 international space flights will have been conducted on five different types of vehicles launched from four different countries."

So, we can roughly compare costs.

Since the space shuttle launches were more expensive than the Saturn V launches (which includes the cost of the expendable rocket), we see that building the international space station using the shuttle, etc, cost about 33 times as much, than if Saturn V's had been used.
