I'm starting to seriously think that moving out to the middle of nowhere and letting my kids run around and play in the woods all day would be the absolute best thing I could for them. Along with a shed to build stuff. I have a six-year-old who is obsessed with YouTube Baby Alive videos and gets very, very upset as we limit her time watching them. It's upsetting for everyone involved as what started out as a cool, fun thing for her as evolved into a daily problem.

I had a borderline unhealthy obsession with legos when I was a kid. It would be all I thought about at school before I got home.

Fast forward a few decades and I've found a nice niche in hardware supply chain. I think play that becomes an obsession can indeed have healthy effects that aren't immediately apparent at the time, but I share your skepticism about YouTube.
