Those people aren't interesting Joan was. She was a focus for change in her time. Why waste resources on someone who did nothing when you can focus resources on the important. Your attitude is very Liberal in that regard.
"Liberal?" Wash your mouth out with soap and water right now! lol However, your points were well made and well taken here. Certianly, Joan was "interesting." And for a study of someone interesting, maybe even seriously disturbed, Joan fits the bill as well as any, maybe, better than a lot of others. :)
