There were many prohibitions placed on Israel after they made the golden calf at Mt. Sinai while Moses was away. These were placed on them due to their own hardness of heart and attachment to pagan things. These laws were, in part, intended to separate the Israelites culturally from the Pagan cultures they were used to and bring them closer to God.
Jesus brought about the fulfillment of the law. That doesn’t exactly mean the end, as if we’re disregarding it. What we mean is that Jesus brought about the internalization of the law. Rather than the law being written on paper or stone, it would be written on our hearts. We were ready to understand that it’s not what enters a man that makes him evil, but what comes from inside him. We were ready to move onto a new covenant between God and man.

The Bible gives us a “salvation history”. It’s a narrative of man’s relationship with God. And in that story, man’s relationship develops, matures, and progresses. Videos like the one you found take bits and pieces from that story and take them out of context and treats them like an arbitrary list of rules.
