If we apply your theory of making Profitable Business & no care for other human Value.

Why not to sell drugs (weed / hasish ) They will also make really profitable business Earn lot of money. Great Idea ?

& make it mandatory to smoke in restaurant while eating because some people like it ... make business profitable. who cares about side effects

Come On ... Even the person who smokes & drinks know how harmful these things are .. They are really weak ... they can't control themselves to get rid of it..

So in that case Gov have to set some rules ..

Hope you understand.
