I know I don't want to work in "this" Hollywood.
I think the idea most of us have, is to make that first sale, hopefully gathering interest in our talent while doing so. Then, there's interest in what we might write next. Most of us don't want to write something that we're asked to. Unless, well, that broken first pitch to the writer has nothing going for it save for the immediate rush of ideas that the writer has upon hearing it... then, it's yours anyway.
I tend to think that writers in general want to do it on their own terms. Whether that means getting a 5 picture contract with a studio, hired for an adaptation, or just returning to the typewriter at our secluded home by ourselves to flesh out our next personal passion. Our own terms. We're a lot of things, but we like our independence, I think most writers, if not all are creatures of this nature.
Lastly, if your intention is only this one project, then it doesn't matter. However, if you want more and after that sale, you have offers or inquiries, then maybe sticking around a few years to get the ball rolling a few rotations further isn't a bad idea. The L.A. area isn't for everyone. Hang out a few years, get some more projects under your belt and then move. Leave. At that point, it's likely they'll work around that decision.
And you never know, you might even come around to wanting to stay. Even if it's just for the weather.
