That is the idea behind "mass drivers" on the moon I believe. Maybe that search term helps.

You can do that but it would require a track that is tens of kilometers long along with a magnetic levitation technology. My suggestion is something we can do right now with a basic landing strip. But yes a meglev is the end game. Needs to reach 8,570 km/h for moon orbital velocity.

You would have to do at least a circulization burn no matter the budget spent on maglev.
