Oh my. Hit a nerve did I? Such hostility.
I'm not going to respond to everything separately again as there's no point. All of your complaints stem from the same general thing; it seems the real root of your problem with XIV is that people can play their characters however they want. And for whatever reason, it just seriously bothers you.
Is it because you assume that with this freedom everyone will play the same way? It just isn't so. To say differently is baseless and arrogant. I already prove your 'everyone will level everything' argument wrong because I'm not going to level jobs I don't feel fit my character. If you don't believe me, check. PUG and ARC remain untouched on Chione.
But even if I'm the only person in this whole game who isn't going to level every job, why does it bother you so badly that you'd rather them bring XI's restrictions into this game?
Why does it bother you so much how other people might or might not play their characters? Why is it any harm to you that you see some rank 5 person in rank 45 gear? What harm to you if the other guy has the same skills learned and equipped as you do? Can you not play the game your way and allow them theirs?
