“Free will” being a illusion fits pretty well with the simulation hypothesis.

Similar to a game of The Sims the char­ac­ters ac­tions are cho­sen in ad­vance.

A string of ac­tions were your last ac­tion effects the next one and were ac­tions are can­cel­led out and changed.

Your next ac­tion is to pre­pare a meal. You walk to the kitchen to start prepar­ing the meal when you open the fridge and no­tice you don’t have any food. The ac­tion is now can­cel­led and re­placed with “Go to the store to buy food”.
