It's the opposite of pointless. It's the way the game is designed. It is inherently the only correct way to play.
Now that does not mean you have to have all roles at all times, nor that you can't have dupes, but simply that performing tactics with your team will provide victory. You can't have 6 lone wolves hanging out in the back trying to snipe people in a payload defense map. It's just not going to work unless the other team is hella bad, at which case it doesn't matter what you are doing.
Teaming up in Overwatch is both constructed and organic. While the roles are constructed, several strategies emerge that offer teamplay whether you like it or not. Even in the extreme case where you run 6 Widowmakers, you'll at least help eachother see through walls 100% of the time. You'll likely lose depending on the map objective, but you know...whatever you want to do.
