The existence or absence of IP laws does not affect your capability to have secret information in any way.
Patents, one of the types of IP, was actually designed to encourage holders of secrets to release them. But the ability to hold secrets is completely unaffected.
Also, just because you hold a secret does not mean anyone owes you anything. You may sell a secret and you always could regardless of IP.
What IP allows you to do is, after you've made a secret public, demand compensation every time other people share it among themselves.
