To cover both of your objections the environmental factor wouldn’t exist if the brain could be reorganized in a way that would make it identical to the original brain. Who you are is your brain. If a brain is cloned exactly that brain would have the same environmental growth.

A clone breathing the air that exists now at an age where you breathed different air is a sufficiently different environmental change to make you not -perfectly- identical anymore. If your clone was a perfect exact clone, there is basically -no- delay between that clone existing, and the first environmental difference between it and how you developed.

And you simply cannot "modify" a brain in a way to make it identical to another brain, since for one, you and your clone will -always- be at a different stage of development and growth (IE. You can't make a 15 year old's brain be magically identical to a 30 year old's brain) and even if you could make them as close to physically identical as possible, we simply don't have the science to duplicate such a thing. If we did, we could be modifying everyone's brain to have the collective knowledge of all the greatest intellectuals.
