Dude, value is relative. You can make this argument about anything. Why buy a nice car when you can buy a cheap used car? Why buy nice shoes when you can buy a set for 5 bucks at the dollar store, why buy a big ass TV when there's starving children in africa, why buy your girl a diamond ring when a plastic crackerjack ring will fit on her finger?
It means nothing to you, that's fine and personally I wouldn't spend 50 bucks on a 1/55 even if it were MISB, but really there's no reason to crap all over someone else just because they value certain things differently than you do.
