Shame, you can't admit you were wrong on constitutionalism even though you so obviously were, additionally mis-read what I said and then hanged yourself with bad google-fu. I'm done here, at least with you.
First and foremost, if anyone has been misreading things, it's been you. I'd be almost impressed at how you managed to misinterpret "let's focus on other parts of the world that are more pressing" as something along the lines of "Jersey is complete irrelevant and should be ignored blah blah blah" if I wasn't so used to it by this point, because our entire debate (and for that matter, your debates with everyone else) has been me advocating patience, or otherwise saying that it would not be a particularly wise use of resources, and you practically going "Help! Help! I'm being oppressed!".
Second, I never said that San Monaco's constitution came before Jersey; just that they came up with theirs on their own, and that who came first is irrelevant in the grand scheme of things. Again, magnificent job putting words into my mouth to give yourself an argument.
Case for Jersey:
1) Place for England and France to fight each other where neither has any home ground advantage.
Unless someone parks an army there and the invader suffers a terrain crossing disadvantage. And since Paradox isn't going to be adding in any Jersey tag anytime soon, it's going to be one-up for England.
2) High historical importance.
In your opinion. Jersey undeniably has stuff going for it, but none of it can be accurately represented with current mechanics (beyond it's Autonomy, which would make it even more worthless than it would already start out as).
3) The government is an extremely rare example of a noble and later democratic republic.
And since there was no Jersey nation and there will be no Jersey tag, all this can be represented as is high autonomy, which again would make it even less valuable, and ultimately it would get reduced to 0.
4) Easy to add events and flavour, due to extensive history throughout the period.
At best, these events would be given to England, and even then, there are plenty of other nations that had far more relevance during EU4's period that are deserving of events than Jersey.
5) A place where other nations can negatively impact and get a foot hold against France or England without actually being in France or England.
Beyond Brittany or a few releasables, I don't think anyone else will be gunning for it. And if Jersey's development would be accurately represented (you know; 1/1/1 grain province with 75%-100% Autonomy), its loss would be literally inconsequential to England or whoever owns it.
But I already know that none of this will make you reconsider your position; so I'm just going to leave you with this to think about: what could an independent Jersey - and I think you've made it abundantly clear that's what you really want - have feasibly accomplished on its own? You know; beyond serving as another stepping stone for an empire.
