That makes sense from the point of view of the Christian narrative, but it doesn't make any sense from the point of view of the human narrative.
It's like saying that God made a guy with a huge dick so that other men don't have to worry about feeling insecure for not having a huge dick. Or he makes an ultra fit guy so that other people can just relax and be fat. How does that make sense? 

I can understand Jesus being an example that other people can follow, and perhaps going as far as saying he is the ultimate man, the perfect being. We could not expect to reach his level, but we should at least try. Now that is quite different to saying this guy is perfect so that you don't have to be perfect. That just sounds dumb to me

It was to prove that it was impossible for mortal Israelites to keep Mosaic law and be saved. Everyone was and will forever be a sinner except God himself, hence the new covenant.
