Yea, it’s a very shortsighted “solution.” My son (8) learned to play piano from YouTube well enough before we started him in lessons that his teacher skipped him directly past the first couple of books. 

 We can’t have 8 year olds learning piano unsupervised from Youtube. 

What if your son had tried to learn Tchaikovsky, he’d probably be a Putin puppet today and you’d be powerless to stop him!
