Holding up in court is one facet. Needing to litigate in and of itself is typically a deterrent, especially for complex issues where there's a time/cost deterrent for pursuing combined with perception of success in court. There's a lot you can get away with by making a process complex, arduous, and potentially expensive. Faced with that option vs letting some employer take photos of you in your pajamas without shaving while watching your every move, people tend to forego privacy. When the working population at large starts to follow suit, you've artificially introduced a new trend with artificial social acceptance. Now, it makes a single employee battle concerned about privacy even more daunting and introduces perception of increased risk of failure if legally pursued for the employee thinking of litigating. The end result is: privacy is eroded. Rinse repeat, for just about anything you want to change. Just make change gradual and give it time. It then takes someone with the financial and time resources to take a hit and pursue as well as eagerness to bother.
