I don't know much about Sonic Youth, but didn't they use prepared guitars? That just means sticking knitting needles and screwdrivers and so forth under the strings or through the strings, attaching alligator clips, paperclips etc, or playing the guitar with unusual objects (I know Zappa used a dismembered dolls leg from time to time). You can get through a lot of strings, but it isn't exactly destroying the guitar. It's also, in my opinion anyway, a good deal more interesting that Yngwie Malmsteen style masturbation.
Unlike say, various people who have just recorded themselves drilling holes in guitars, and other things.
Though, really, at the end of the day, most guitars are produced on a production line. It's not like burning a Stradivarius. You might as well get all weepy about people blowing up cars to make action movies.
