That is good advice because it's better for humans to seek an independent mindset which desires separating from a starting point which is generally our parents. Jesus used parables and I love illustrations myself. People should seek after a personal perspective that can be developed from the inside-out. So, kids should get out of the house, both literally and also mentally as well. They got to get out and grow up. That is why I love Stefan Molyneux and philosophy. People should know why they believe what they believe as opposed to only saying "I believe in whatever my mommy and daddy told me I had to believe." There should be individual freewill choice.
