Should smurfing be banned?

I'm trying to get out of bronze with my really low elo account, I know a lot of people use smurf accounts to get an advantage over lower elo players making it much harder for them to go up.

Here's why I think smurf accounts should be banned:

• The elo does not represent the player's true ability
• reduces the chances of players to get out of bronze
• usually they get a troll pick, i.e. adc trynd with smite pissing off their entire team, losing the focus from the game
• if theres a smurf on the enemy team, it makes it really hard to defeat them no matter what

I know a lot of you might disagree, but it really is unfair to lower elo players.

I hope riot can do something about this, since its been bothering me for a while.
