The only people who the real name policy punishes is the real users. The ones who do everything right. The ones who do not wish to have their lives outed this way.
Now I'm gay, and have no problem being out online but at home in public is another problem. I've never moved from my Childhood home and I live in a small town, its pretty easy to know who I am, so I made it a policy to never link the two so I don't have to do deal with Homophobia on my Doorstep. Its a small town and news soon spreads. I don't have a Google Plus account and am moving away from Gmail for this reason. I never ever use a real photo online. Facebook is only used for minor things on an anonymous email address with a blank photo. Even then I hate it and do not use it for personal stuff.
If you are really concerned about privacy, just delete your Gmail, Google Plus account. Get your wallet out and move to a paid alternative where you will not have to worry about having your email connected to a social network. Buy a domain name, use a private whois service like at NearlyFreeSpeech.Net so you can move between providers over the years but keep the same address.
If you really must comment on YouTube, create a Google Plus profile on a brand new Gmail account for those exact purposes. Understand that anything you write online can be traced back to you. We are not anonymous despite if you never use a real name. Google knows more about you and your interests than any other entity and it has years of your surfing and searching habits in its database.
Edited to add, if you hate the comments on your own YouTube videos, just turn them off.
