My puppy likes to chew

I’m starting to feel like the people who tell you not to tell your dogs NO, are the people who never tell their toddlers and young kids NO, I’ve been trying to do positive reinforcement and switch to a toy for chewing and my pup thinks it’s a game, I started telling him no when chewing on things and he backs up now immediately!! So what now? From now on I’m not listening to the sensitive new age people, I won’t discipline my puppy, but I am going to tell him no from now on!
