If don't have a length restriction, the majority of people will still use more than that and he has to look.
Sure, but security should work for everyone, not just the majority.

Without a length restriction, a significant minority will pick short passwords. If there are 12 people that can access my credit card information, I'm not satisfied if the majority of them picks a long password. I rather want it enforced that all of them have a long password; I think that outweights the 17 seconds an attacker gains.
