I see your rationale, but I prefer to attend the event. The whole undertaking is about supporting your local store, and in turn, its employees and customers. I enjoy RSD events at my local store.
I got to this year's RSD about an hour before opening and got a really good place in line. It really was a lot of fun BSing with others about the new releases, collections, concerts, and audio equipment. There were hipsters, jam-band phans, punks, metalheads, and for the most part, non-descript music geeks. It was fun to see similarities and differences in people's appreciation for music and approach to collecting. The shop owner stopped to chat with people in line as well.
