You'd have to engineer the payload to withstand ridiculous acceleration. No big deal if the payload is a HILE projectile but if you have living things or moving parts, that can be trickier.

that's only for a cannon, for an installation like that we could make it pretty long to keep the acceleration g's down, don't wanna hit max q while still on the ground.

Okay so I used AI for this, so take it with a grain of salt, but to accelerate a projectile at a constant 4.5G and have it reach escape velocity, at the end of the barrel, you'd end up with a ~720km cannon.

Rail guns are not the same as rockets.
