Gravity is not "harvested", it just stores the energy briefly. Someone or something has to lift the weight for every shot, which requires energy.

It's not obvious whether a trebuchet is better than compressed air, like a BB gun.

All harvesting requires some secondary-energy source.

Gravity is a resource, it takes effort to convert it to a form that can be applied - just like wheat, photons, air guns, etc.

True, it’s not obvious yet, but it sure is fun following along and imagining the final, highly optimal version making its way through the process. I’d use it for some seed bombing hijinks, anyway. Green up the place, I would.
