Why do you assume that we are not "down the road a few years"? Your attitude seems to be that everyone talking about the benefits of a light bike have ridden for a week and are choosing between a Nashbar entry level bike and a Wilier Zero 7. Maybe you're at the entry level position so you can only see this discussion from a personal pov.
