liability for people improperly discarding your products is unlimited; there is no limit to how much damage they can do, and there's nothing you can do to stop them except screen your clients very carefully
and that's why, for example, armadillo aerospace went under; vendors of rocket-grade peroxide do screen their clients very carefully, for precisely that reason, and they had to scrap their peroxide engine design and go back to the drawing board
industry is going to happen instead in places like china where it's allowed (at least for chinese people)
