The ISS can stay above the earth by orbiting fast enough, just like a rock tied to the end of a string. If you spin it round and round fast enough, it won't fall to the ground.

That is just plain wrong. A rock on a string spun in a horizontal circle doesn’t fall to the ground for the same reason that a rock on a string hanging at rest doesn’t fall to the ground - the string. If you took a snapshot of the rock and the string you would see that the string, even if it looks horizontal, is actually at an angle. If you measured the tension in the string and resolved to find the vertical component of the tension you find that it equalled the weight of the rock, exactly the same as the rock at rest hanging vertically. The faster you spin the string, the steeper the angle, just like a motorbike cornering, or an aircraft banking into a turn - the vertical component always equals the weight if the vertical acceleration is zero.
For the ISS to remain in ‘orbit’ above a flat earth, you would still need something holding it up there - the string, if you like. Aircraft do it by having wings - the ISS clearly isn’t a lifting body, and even if it was, it clearly doesn’t have the propulsion necessary to overcome the drag that generating lift causes.
You also have the problem that the ISS isn’t moving in a circle, if you plot its path on any of the FE maps - both its speed and its flight path change. This is of course nonsensical, as the ISS’s observed speed and flight path from ground is constant, which is hardly surprising given that it is essentially ballistic - it ain’t changing.
As for the holograms…that’s just plain fanciful. Are we really suggesting there is some massive team of people somewhere who’s job it is to project holograms of all the satellites, remembering it’s not just the ISS, onto the ‘dome’? And they presumably also have to fake all the comms as well? Did NASA establish them as soon as the Russians launched Sputnik, so that all the amateur radio enthusiasts could hear Sputnik’s signal at the right time?
