I agree with the creative spirit answer. The objective is not to make a "blanket." It's to exercise our artistic soul, challenge ourselves to a higher perfection, to mastering the difficult, or just to revel in the joy of color, fabric and pattern. Many people have a passion that makes them feel more alive, more purpose to life, happy, whatever the adjective they want to use. I think it's awesome that we have so many different passions and pursuits. Makes the world a more interesting place!
