Why do people make such long and mostly useless how to videos on youtube?

I just want to know an easy way to get the backing off of a piece of carpet tape. I found this video that’s 5 minutes long and the first minute consists of her saying, “Some people have a problem separating the liner from the tape,” in 8 different ways. Why can’t I just click on it and have my answer in 10 seconds? Why do they talk so much?
