What would happen if corporal punishment was permanently banned worldwide?

Hypothetically speaking, if it were up to me to sign a law that enacts a total global ban (on every single country, islands, continents... the whole world) and my answer was the one that counted the most, I would definitely do it in a heartbreak.

What would happen if this hypothetical scenerio took over:

All of the sudden it isn't just 65 nations that prohibited physical punishment on kids and teens on all setting but the entire world. The child and others can report their caregivers for using a belt, slapping them or other weapon of choice and they either have to pay a fine or served 1-2 years of jail time, followed by a mandatory anger management and parenting classes.

What do you think would happen if a drastic change like that took over on all nations and it stayed permanently?
