What consequences does an apple have?They reversed time on specific objects multiple times. Strange did it on an apple, Thanos did it on Vision, which was also a major plot point. Neither of them had an effect on anything else. They didn't follow their own universe's logic.
Thanos used the time stone to bring the mind stone back, and it DID have an affect on other shyt, bringing the mind stone back reversed its destruction and brought Vision back with it, so he had to kill Vision a 2nd time to get the mind stone. You're talking like you could have reversed Tony doing the snap without reversing the effects of the snap.
You see how weak your retort is? There was a REASON that Strange didn't tell Tony the way ahead of time. He could prod him forward at the right moment for the exact same reason. You don't want it to be a reason, you want everything to be like magic spells or some shyt.
