I don't think this is unique to backpacking. Think how often something similar happens at work (or when dealing with aging parents - or so my kids tell me.) People tend to feel most comfortable with what they are familiar with (sometimes I think inertia makes the world go round.)

I've always said the six most dangerous words in the English language are "We've always done it that way." (Or, if you prefer, substitute "never" for "always" - same result.)

The only attitude I can tell you to adopt is "Illegitimi non carborundum."
