Yes but for each swingset purchsed using state funds for a homeschool kid provides for 1 student whereas each swingset purchased using state money can provide for multiple classrooms of students.
That homeschool swingset is now private property not useable by anyone else that helped pay for it.
People choose homeschooling, fine. Homeschool should never be funded by the public, unless public school is not available or the student cannot attend for legitimate reasons.
You choose to homeschool? Great, you homefund it, too.
