This is unrealistic. If it were easy to root an iPhone, then we would reach a situation where app developers would stop releasing necessary apps in the App Store because they want to bypass all the ethical behavior it requires. It would effectively force everyone to the lowest common denominator.
If it were possible to root an iPhone, Facebook would have never agreed to give users the option to stop tracking them across apps; they would have instead said “please watch this video and do what it says to continue using Facebook/Instagram!” and guide naive users into rooting their phones.
Closed ecosystems have many advantages (and disadvantages) over open ones. However, a closed ecosystem with a gaping hole in the wall is no longer a closed ecosystem; you can’t have it both ways.
