1) Teachers are supposed to come up with those lesson plans for their classroom anyway. So what if they want to distribute it to other teachers? If the school or the state wanted to control the lesson plan content so tightly, they'd design their own plans and foist it on the teachers, which you and I would likely both agree we do not want.
2) Even if taxpayers do pay teacher salaries, they do so using local tax revenue for educating students in their respective state and municipality. Once this lesson content is consumed by students and teaching is complete, what is the benefit of the taxpayer usurping this content, and for what purpose?
