First, the Saturn V did lift off several times. There are movies of it, and there are thousands upon thousands of eye-witnesses.
The tooling for making the F-1 was discarded along with the updated drawings. It was very expensive to make the tooling, let alone the design of the engine itself. NASA does not want to resurrect it on the grounds that newer designs are easier to tool and make; and, they would provide higher thrusts. The only way to recreate an F-1 engine is to scan it with X-ray 3-D imaging devices to see how the later versions were made.
You do know that NASA did not actually develop ANY of the Mercury/Gemini/Apollo hardware or any detailed designs, don't you? Every scrap of it was developed by contract companies. The F-1 engine was developed by Rocketdyne. Once NASA no longer needed it, they were free to dispose of all production artifacts. A few clever souls siphoned off historical artifacts.
Your referenced article is so very wrong. It would take a lot of effort to tear it down. Since I already know that such an effort is wasted on people like you, I will go no further.
Fair enough—but when nations and private companies spend billions more dollars and many more years and still can’t get it done, just remember our discussion.
