> things will tend to become more disordered over time
Only if they weren't disordered to begin with. If you start with well stirred coffee and milk and stir it again, it won't be more "disordered" than what you started with.
The problem is that our universe started as "ordered" for reasons we don't understand. We call it the big bang, and that's the origin of the arrow of time.
No big bang means maximum entropy, no arrow of time, and no conscious observer. And if there is, that would be a Boltzmann brain scenario, and no one wants a Boltzmann brain scenario.
The question of the arrow of time is literally the last question of life, the universe, and everything.
