Warehouses don't want asbestos- the asbestos doesn't serve any purpose. It's just toxic waste.

Are you kidding? Do you think that companies decided to place asbestos in buildings years ago just because it was fun? Or maybe it's a form of spontaneous asbestos generation?

Asbestos was, and is, one of the best thermal insulators and fire retardants in the world. It is really only friable asbestos that has been banned (for good reason), which occurs mostly in pipe insulation and ceiling coverings. In fact, non-friable asbestos is still used for many applications, including such things as automobile and elevator brakes, roof shingles, and floor tiles.
