The reason being that contrary to what Riot believes, most pre-mades do not know the person irl, or have any influence on the person's internet/PC. I find it funny that if i decide to play a game with people on my friend-list(because riot encourages it and punishes solo play) and they DC it is somehow my fault. Not only that but this system promotes abuse by forcing the pre-made that didn't DC to say no since they will lose LP 100%. What in the world are you thinking!?
