wildlife photogs have to worry about branches and brush scraping elements too. There are many reasons to protect the front elements. But the average shooter doesn't. I don't mind using my shirt to gently brush away dust on my cheap filter, but I wouldn't dare do it on my lens. I do carry a microcloth in my domke bag, but it is a pain to get out all the time, that is IF I didn't have the filter protecting the lens.
