Because if you comment out the code you don't benefit any more from the compiler checking that the inner block is still legal, or from your IDE to do the refactoring operations you want. The code would bit rot much faster in a comment (or removed from the code base altogether).

The thing I really can't understand is why you would compare a boolean condition to `true` instead of checking the condition itself (in other words, writing `false` instead of `true == false`). Also, let me suggest to use `&&`, not `||`. And while we're at that, I would actually write:

    if (false && my_var == 'some value') { ... }

just in case operator `==` can have side effects or relevant computational cost in your language.
