An eleven year old shouldn't be uploading content to YouTube. An eleven year old doesn't understand the second or third order consequences of their actions when they upload a video of themselves, along with their friends, trying on bikinis in their bedrooms.

Your kids talk to each other at school without parents going over their conversations to make sure everything is kosher. Interacting online isn't any different, as long as they know not to give out their physical location publicly or to strangers. Even more so these days, kids are digital natives. Cutting them off from the network is like giving them a lobotomy. They'll be well behaved, obedient, sessile outcasts.
Anyway, interacting online is so little like running free on the highway that it's difficult to even find a foothold to frame a counter-argument. It's a non sequitur.
