I think, borders should be taught in a different way - not by biting in an ear (yeah, works for cats, though I prefer water or the noise of a newspaper heavily rapped on the table).
We should be able to teach borders and respect of the rights of others differently - agreed, though I am far away from the perfect solution.
But what you are saying as quoted is replacing one form of violence with another - and this is similarily true in "modern" child education; physical violence is banned, and more often than not replaced by psychological violence. In my personal feelings keeps creeping the suspicion, that the damage done to the "educated" is worse.
