Sounds like a bit of a straw man to me. It'd depend on just how big the difference in the number of keystrokes there are, would it not?
Do you not agree that writing 100 lines of code instead of 1000 lines saves time, when writing it but perhaps most importantly when reading it and developing it further?
I'm not saying CoffeeScript cuts down the number of lines of code by a factor of ten, but, depending on what you do with it, often by 50% or more.
Making it about "keystrokes" is a bit disingenuous, it's about cruft (aka "keystrokes") but it's also about lines of code, imho.
