I don't agree with what you're saying. The question was "Should parents use spanking as an option to discipline?" It never said they would get hit for everything. You will need to spank your child for some of the most serious things they do because if you don't they will think it's not that bad.

I agree with you because what you said is true. A child will learn once they've been spanked.

Yes, because they need to learn in a way that they remember that if they do something bad. They will get hit.

Yes, there is an appropriate age to stop because the child will be going to school soon and you wont be there. He/she has to get unattached to the breast milk. So mothers should teach them from the start that they wont always have breast milk to drink.
