Looks very interesting but I see one obvious issue that may or may not be significant --- any satellite to be launched will have to be built to withstand the 10000g launch.
Relativity Space is building 3D printers large enough to construct orbital-class rockets in one piece. Others will follow. If they can make printers work in vacuum at 0g, that's how we build our next-next generation of space stations. SpinLaunch wants to launch around the clock, multiple times per day. Just keep flinging materials and consumables to the construction robots building our future habs.
We've been launching electronic devices by artillery since WWII - those with proximity fuses - without transistors!
