Where we're going we don't need railguns
>In theory, it is possible for a magnetic sail to launch directly from the surface of a planet near one of its magnetic poles, repelling itself from the planet's magnetic field. However, this requires the magnetic sail to be maintained in its "unstable" orientation. A launch from Earth required superconductors with 80 times the current density of the best known high-temperature superconductors as of 1991.

Once we massively improve this (maybe) superconductor rocketcucks will be on suicide watch and far northern Canada will have a massive spaceport
