Leaving aside all the doctrinal issues it would have to be the control factor.
Grooming laws... no long hair, no facial hair, no individual style of any kind. For sisters, no pants, no short skirts, panty hose required, no short hair (men style).
Entertainment laws... no R-rated movies, no 'debasing' music, no trendy books or magazines.
On and on they went.
And for the sticklers out there, yes, there were no actual rules or laws that forbade those things, just elder counsel and peer pressure. But they were unspoken laws nonetheless. Try wearing a beard to the KH for a talk and see what reaction you get. I did... It was as if Satan himself came to give the part. Try wearing your hair long, over your collar. Count the elders that want to speak with you after the meeting. Sisters - wear a skirt that comes up over your knee, or maybe a slit, or maybe an undone button on your blouse.
Leave a heavy metal or rap CD laying around your car when it's your turn to drive in service.
Leave R-rated movied laying around on Book Study night.
See how long before you're 'counseled'.
Laws? Yes, indeed.
