Your daughter is wrong. We all need some sort of hobby or something we love to do. I have done crocheting, I have a needle point that I work on from time to time.
I just picked up on quilting and I love it. It's a challenge, it's relaxing and I love to see the finished product.
Your quilts will be treasured always.
I've worked in Nursing Homes and places like that, whom would love a donation of quilts for their seniors and the ill. Childerns hospitals, there are tons of places to donate some of your work if you so desired.
Keep up your work, and do what you enjoy doing.
