Well, some kids might get drain bamaged and end up wards of the state or something, Hungry Seagull.
I do have the solution:
1. Freedom to do whatever you want, as long as you don't do it to anyone but yourself or other consenting parties.
2. Tax-funded health care for those who damage themselves beyond repair through their own actions. It would consist of the best, most painless euthanasia that science knows about.
I honestly don't think that all the laws in the world, that often end up unintentionally ensnaring those of us who don't need to be saved from ourselves, can stop those hell-bent on removing themselves from the gene pool. Natural selection is important; why try to stop it?
WRT this law, this does mean that someone who takes a pink water gun and spray paints it black for a school play is now a criminal even if he destroys it after the production is over. That's what I mean by "unintentionally ensnaring."
