Because, quite simply, you don't use adsense. Let me put it this way. Let's say tons of people use an adsense. Now, it is better to have a bigger adsense that generates more money. You and I see this, so we start monetizing our stuff on the same adsense. If you and I each make $10 a month, our adsense reports $20 of earnings a month, meaning we'll get paid faster.
Now imagine that is done by 10,000 people. Basically, that's a network. You allow someone with a really big adsense to add your channel to their adsense. And as I already said, the bigger the adsense, and the more regular revenue there is, the less likely one "false" click is to sink the boat. It's still possible for a network to get disabled, but it's about as likely as the sun exploding tomorrow.
There are other benefits, as well as some bad things, but that's the basic idea of how a network works.
And don't worry, this whole "false views" thing won't get your channel taken down! At worst, your adsense would be closed, but the channel would remain. Do you get ads with adsense right now? If you want to monetize gaming videos, I'd recommend joining a network, as they're less likely to get in trouble for these claim ordeals. If you use adsense as a gamer,
stop immediately!!!
