I think you would expect to see differences. You've made 3^^^3 days slightly worse, and there's no way that none of those slightly-worse days had knock-on effects.
But I'm also not sure it matters. If something is bad in-the-moment, but has no knock-on effects, that still seems bad. If you could torture me for a minute, then erase my memories and replace them with memories of a minute spent doing what I was previously doing anyway... I would accept that for some amount of money, but not for a penny.
Change the game slightly: in one world, torture for fifty years and then the person dies, they don't interact with anyone for any of that time. In the other world, dust specks, but also one person is locked away for fifty years, not interacting with anyone, and then they die.
Which do you choose? Sixty years from now, which do you wish you'd chosen?
> I wouldn't pay a penny to avoid the dust speck
Do you mean just your own dust speck? The question was all 3^^^3 of them.
If you do mean all of them... I would pay a penny to avoid dust specks in seven billion eyes, let alone 3^^^3. If one could press a button that would put a dust speck in the eyes of everyone currently alive (at some future time where they're not operating machinery etc.), and in exchange the presser would receive a penny, I would not press that button and I'd be pissed off at anyone who did. (Maybe not anyone, but at least anyone who isn't struggling to live.)
