Hehe. Nice analogy. What I'm saying is that if you are in a tight space then maybe you shouldn't use the hammer. Complaining about the hammer not working in tight spaces is not going to help anyone. Unless of course someone then invents a hammer that does work in tight spaces...and then tries to show how the new hammer works better for everything.
I believe that all they're saying is that a hammer might not work well for all situations (crowded spaces, for example), so they want to invent a new hammer that does work well for all situations (like crowded spaces).
