...an if the IDE is already that smart, why should it still require me 
to comment out code just to make some other part of the program run?

A programming language environment should make programming as convenient 
as possible, not in some areas convenient and in some other arbitrary 
areas less convenient.

(And if you think that static type checking makes programming more 
convenient, then yes, why not? Add that as an additional option! But 
make it possible to switch it on or off on demand!)
