I think your quilt is without a doubt worthy of being finished. If you don't want to quilt it, maybe you can pass it on to someone to finish.
I have one quilt top that is really bad. I could see things weren't working, yet I kept on with it (have you ever started painting a room, and you see that the color looks bad, but you tell yourself, 'it will look better when it's all done.' Not!) When its time comes, I think I will quilt it for the practice, but I don't know what I'll do with it after that. Maybe keep it for moving furniture.
