These are not coherent reasons why it would be different, they are assertions that you think it would be. None of them even speak to any difference between the platforms.
Just saying that it will be isn't a reason. None of this has happened. Every attempt at doing this has failed horribly. Most users are not technically capable enough to even go about installing an alternative store.
Why, given that this has not happened in the case of the leading mobile platform, and in fact all attempts to even mildly break with the play store have been resounding failures, would iOS be any different?
