I was circumcised as a newborn back in the day when every boy was. I have had no complications. Plus I never need to clean schmegma daily. I don't have to worry about infections. I don't have to worry about stretching irritation.
I think Dad's using a loophole to be a controlling person. He should think what it may do to his relationship with his son down the road.
It's just soap and water, and takes barely 10 seconds while in the shower. It's not like as if those who are in their natural state undergo a lot of trouble for being left intact, at least not as bad as you've pictured it to be.
Quite the contrary, I would say. Especially considering the numerous nerve-endings present on the foreskin, which stretches and inverts to become the sides of the penis while "in use".
