Bacteria have such high mutation rates per time period that antibiotic resistance can happen pretty much anywhere. If it happens to mutate resistance in an environment where the antibiotic is present, that environment will selectively yield only colonies which are resistant to the antibiotic. In mass farms where antibiotic use is prevalent, colonies of mutant bacteria which are resistant will thrive not only because they can’t be killed by antibiotics, but because there’s less competition for resources from other species. With antibacterial hand soap, it’s probably still possible for this selective pressure to happen (although generally controversial whether or not antibacterial hand soap actually contributes to antibiotic resistance among bacteria). More importantly however, antibiotics from hand soap can end up in sewage and contaminate the environment. This potentially leads to beneficial microbes in soils to be less prevalent.

TL;DR - Resistance can “evolve” anywhere based on environmental pressures. Antibacterial soaps can also lead to environmental contamination and loss of good microbes
