Looking for feedback (especially from other teachers)

I teach middle school music and I want to try to make my classroom a laboratory in liberty...or at least to the extent that one can do that in a government school. This is a PowerPoint that I'm planning on showing on the first day of class (in September). The idea of this specific presentation is to start talking about rights as soon as possible. I touch on music at the beginning because otherwise they will be totally confused. There will be much added verbally to this, but I wanted to get some feedback from DP'ers about how I'm presenting the principle of liberty.

Also, I should point out that I'm aware that the first slide, telling kids to sit in their assigned seats seems rather anti-liberty. Without going into all of the details why this is necessary, let me just say that it has something to do with property rights. I'll be explaining that in my next PPT for the second day (which I also plan to post).

I think it's very useful for those of us who teach with a pro-liberty philosophy (especially in the government schools) to network. We are the antidote to USDOE indoctrination.
