Because it is ours. Always. You are a channel to give birth what is there to be birthed into life. Everyone who is on this timeline in this reality gets to enjoy that what you have gifted into the world, not only you. Monetizing and attempting to copyright and patent your stuff is a story of old life that kept us stuck. Detach yourself from the thoughts of possessing something you have created. Once it comes out of you it is not yours to control. Is lives its own life, whether you like it or not.
