In addition to the purposes stated, I think banning anything is used, not as a stated goal, to increase dependence by the people, on the government, with a result of power transferred to the state, from the people.

I have not, so far, come up with any ban that has produced positive results.

It is possible that some of the religious and cultural taboos and prohibitions on such things as having children with family members, and eating certain kinds of foods before refrigeration and germ theory, may fit the definition of a ban, and may have been some of the drivers of increased lifespan, and leisure time, in which to think and refine methods of production for still more increase in productivity and survival.

If we can call these 'bans' then yes, it is possible, but giving people good advice doesn't seem to be a ban necessarily.
