EDIT: I feel delighted that my post received so many thoughtful and enthusiastic replies. That being said, when I posted this poll, the question I have in mind is "why should ZOS decide not to include jewelcrafting at launch time" . Many have given very informed explanation about why ZOS failed to introduce jewelcrafting after launch (balance sort of things), but I will appreciate more if you would share you opion about why ZOS didn't introduce it at the beginning.

Why do you think we don't have jewelcrafting? 154 votes
ZOS want people to participate in PVE content, so they make it with intention that no one can equip two 5/5 crafting sets.
Short of budget, might be introduced in the future
The current Crafting skill lines are very symmetric, ZOS have got OCD and they don't want to break such symmetry
