Just to give some motivation, think that top Youtubers like RWJ, Nigahiga and Smosh make at least 3k-5k $ per day just by video views only.
But it's not just that, in my opinion the best advantage is that you are creating a brand on yourself. So, you can make also TONS of money by selling tshirts and merchandising related to yourself or your videos.
Think of it this way: if you are earning with some blackhat method, you can see your 1k per day banned from one day to the other and you have to start from scratch. On the other hand, if you create a brand on yourself, you are golden for life.
Some weeks ago RWJ got rightfully banned based on what YT policy says. An average user would have lost his channel forever. But he got reinstated after some hours because he is a HUGE brand.
And, if YT would have been stupid enough to let him go, he could have single-handly create his own video platform to stream =3 and reroute there his millions and millions of YT subscribers and FB/Twitter followers.
So, on one hand creating a legit YT channel is a ton of work, on the other hand, once you reach a certain level, you are on a totally safe ground for the rest of your life (your videos will keep receiving traffic and growing FOREVER!

).
