What am I missing? (easy money on yt?)

After reading here for a bit, it seems to me that the following is the best and easiest way to get money from yt:

1) find a niche with low-ish monthly searches, low competition but high cpc
2) make some videos for the niche
3) buy views and likes and outrank the other videos
4) get an affiliate program for the niche
5) ???
6) profit

What am I missing? It makes sense but it seems to easy. Am I overlooking anything?
