A content creator has other options. YouTube pays per click/view. Amazon pays per minute/hr watched. But, given what essentially is a no-cost entry, it's a tough go to make a living off it.... As for anyone "paying" to watch your video - how many YouTube or Vimeo videos would YOU have PAID to watch? Ever? Just think about that before you buy into their promises of revenue.
Of course, one can also self-publish a book on Amazon. Much like with the videos, it'd work much better for an already existing and well recognized brand.
