I don’t understand how you could interpret it that way. That is completely the opposite, Jesus is saying that some of the Deuteronomical and Levitical laws ARE wrong.
God made it simple, he gave them the 10 commandments but to them it wasn’t enough they decided to go against god and make their own rules, 644 to be exact. The only laws that they needed were the 10 commandments but they chose to make it complicated. Jesus came to correct that to accomplish the old covenant and open the door to heaven.
