If Ifa is the true religion, why is it a closed practice?

I am not saying Ifa SHOULD be an open practice, i'm just curious about the following:

If Olodumare made existence possible and Obatala created all humans, and every human has an ori, then wouldn't God/the Orishas want every human to be initiated into Ifa, so that everyone (no matter their race or ethnicity) can fulfill their destiny and connect to their personal Orisha? Again, i'm not saying Ifa should be an open practice. I'm just curious because doesn't this make it harder for people to fulfill their destiny?
