That depends on whether you are getting the "beer" for the flavor or for the alcohol. If you want something that mostly tastes like beer, but has no alcohol, then the non-alcoholic stuff can have a place.It is like buying non-alcoholic beer: There is NO point!
Examples of who might want the flavor without the alcohol: anyone below the legal drinking age, pregnant women, anyone who intends to drive before the alcohol would have a chance to wear off.
