It has little to do with evolutionary pressure and more to do with water, surfactants and friction in the right application works very very well for antimicrobial purposes and the addition of antibacterial chemicals is potentially harmful to you without benefit(this is why Europe largely banned triclosan soap). There’s nothing we’d really lose by encouraging resistance to these chemicals, the metabolic demands to resist them would include things like spore forming. That doesn’t just appear in a plasmid with some selective pressure like antimicrobial resistance.
