>you dont need something like this if theres an infinite amount of possibilities
Getting from A to B still takes causal change to impact the morphic resonance. Our brains keep us in a relatively strict track and it's much easier to get somewhere if you have a path there, because it's not about actually getting there, it's about changing the percentage of your preexisting linkages across time which get you there. It's true that in an infinite universe a version of you is already there, but a version of you is also everywhere else, including where you are now. If you want the you now to get to some other destination you have to do something to move yourself there.
