Many things are antibacterial and work fine on your skin, but not in your body. Drinking hydrogen peroxide for example would be at best pointless and at worst harmful.
I think GP isn't trying to say that antibacterial soap should be illegal because it's harmful to humans, but that it should be illegal because it creates resistant bacteria.
If it’s not medically useful, I don’t see the benifit of avoidance.
Bleach is a highly effective antibacterial substance, it’s also toxic but that’s not a major problem for floors. Hell, bacteria have had billions of years to adapt to sunlight, it still kills them fairly quickly.
