If you could just be in the general vicinity of a minion, and get gold from it; that would be pretty boring -.-; It wouldn't keep you alert.
But think about other games that don't have last-hitting as a core mechanic, or at least something that you don't have to pay attention to. For example, most RTS games don't favor last-hitting as strongly as LoL does. They provide engagement in different ways, like greater focus on positioning, or concentrating on controlling a particular space, or greater resource management. Taking the attention a player focuses on last-hitting and allowing it to be used somewhere else could be pretty interesting, depending on what the "somewhere else" is.
