You forget the mass driver has much less mass than the Earth. Its pushing against the Earth when it fires- in essence using the Earth as its reaction mass. It would only impart the momentum it gained in relation to its mass when it fired on the Earth.
In other words the force required to send the mass driver to the moon is far less than the force required to send the Earth there.
