We provide them a home, and in return they protect and clean us. They don't want to destroy their home, they would die, too.
Sorry but that is absolute, unmitigated rubbish. I spent 2 weeks in intensive care, with a surgical scar from my sternum to my groin which de-hisced (burst open) because my own bacteria tried to kill me.
While they might be symbiotic in the right place (eg. the gut), they'll kill you pretty quickly if they get out.
