It's not the stupidest idea ever: I want to build a mega-slingshot for commuter purposes (and squirrel hunting). At least your idea has some possibility of controlling acceleration forces, and having the subject/ammunition survive the actual launch.
My idea is still more economical to prototype; which means I'll be first to the important step of courting investors; and of course after that who cares if the idea ever happens or was even possible to begin with.
