In all reality...
Hell yes I would keep writing.
Sure, the dream is to get published and make a nice living at doing what I love, what I need, what - in my opinion - I was born to do, whether i'm any good at it or not. But not a single word I have ever written has been put to paper with the assumption that it would eventually bring me wealth and fame. Hell, I don't even want wealth and fame. That isn't why I write. It would be nice to make money doing it, that way I could quit my normal job and just write all the time. That's the only reason I want money from writing.
In reality, I hope to get published, because what else is there to do? I love writing and will always write, but face it...no single person can tell you that you will never get published. No group of people can tell you you'll never get published. How many doctors have told how many patients that they'll never walk again, and then in a few years, that same patient passes them on the sidewalk, striding defiantly in the face of medical science.
I tell MYSELF that I will never get published, and that's much more discouraging than someone else telling me. It's a much greater battle to convince myself to keep writing when I hit those spots of doubt. Even if Stephen King came to me and said, "Just quit, you'll never be a successful writer" I'd thank him for his input, and show him the door, and then return to my keyboard and keep typing.
All I ever wanted to be is a writer...and I'm already that. Have always been a writer, since I first learned to manipulate the alphabet in Kindergarten. To be a successful writer would just be a bonus.
So, because I'm not writing for the material rewards, getting published and making money are really not that important in my passion for writing. I write because I love to write, because if I don't write, I feel off-kilter, like I'm truly wasting my life. And really, I don't think I have a choice but to write. It's simply what I do.
Would a dog stop pissing on lamp poles if you told him he'd never make any reward from it? No. He doesn't care about reward. All he knows is that that lamp pole hasn't been peed on yet.
Dogs pee on things. Cats meow. Birds fly. Fish swim.
And through hell or high water, for richer or poorer, writers write.
