Only people in a capacity of authority do the same thing to adults all the time when they're hard to control / reason with: imprison them, beat them and pin them down when they are unruly, restrain them, taze them, some countries have corporal punishment, and several other things besides.
What many modern parents did is exchange some slap and/or light hitting (which is not the same as abuse) with an arsenal of psychological manipulation, negotiation tactics, and guilt-inducing talk to get the kids to cooperate. Or, perhaps worse, giving up and letting kids having free-reign and ending up as horrible unsufferable me-me-me adults who think the world is there to serve them.
