I think I get what you’re saying but it is a little bit beyond me.

I still wonder if the problem doesn’t come down to Free Will itself. Regardless of what universe one is living in, if you have only two people in it and they each have free will at some point the free will of one is going to intrude on the free will of the other, and they’re going to require some kind of negotiation or polite accommodation. Some kind of social interaction.

And if one doesn’t take this action but instead proceeds with one’s free will regardless of the other’s free will there is a problem that is inevitably going to exist no matter what universe exists.
