The point is not that helmets do nothing or that you shouldn’t wear them. If you fall off your bike and hit your head, it’s obviously much better to have a helmet on. At a personal level, if that’s what it takes to get you riding, by all means, helmet up. 
Stuff happens...
By the same token, if wearing a helmet is going to keep you from riding, by all means, ditch that thing.
When you weigh the health benefits against the brain-injury risks that come with cycling, it is more valuable for people to get out and ride, regardless of whether they wear a melon shell.
*Disclaimer: I am a full-on helmet nanny. You will not see me riding without one. I ride with several folks who choose not to wear a helmet. We have no issues, between us, about it.
