We only do it at the beginning but players do it because of two reasons :
1. the most important one, the development. You need to kill enemy minion in order to win gold. And in team fight you don't have time to farm
2. To oppose each player of each team

But it's fun for people who like winning and taking games seriously. Playing LoL is fun in the same way it's fun playing in a sport tournament. You have fun but you're playing seriously. That's why you love it or you hate it ;)
