Without emails, it takes all of 3 seconds to sign up, and you never have to think about it again. I'm not sure what the issue is.
Do I then know who posts what? Yes, but broadly-speaking that's generally true for imageboards already, and it neatly sidesteps the issues that arise where you have a group of people who know their way around a VPN but have software that largely revolves around handing out bans via IP addresses. This way there are no wrong bans (unless you somehow get your credentials stolen and someone posts on your account, which shouldn't happen since your username won't be displayed anywhere) and everyone who wants to use a VPN can do so without their usage putting the site's well-being at risk.

It also opens up the possibility of users who have been around for a while getting things like a spot in a moderator election, which is something I don't think I've talked about here, but have at length on /g/.
