Yes, so we're talking about someone who would be committed enough to resisting authority to provoke violence. This is different than saying "if you break a law, it will result in violence" or even the more extreme "instituting a law is a violent act", which is what the original comment in this tree suggested. I realize what you're saying, but I think at this point it's argument just for argument's sake.

Also, in this case, the individual dosing livestock with antibiotics is actually harming society, in which case I think it would be okay to physically detain him/her from doing so, rather than just saying "this is just too much effort, guess we better let him do whatever he wants". In most scenarios though, I don't think this would be necessary.
