The thing about languages is that they are constantly changing from generation to generation. Any official attempt to standardize a language effectively fossilizes it, and the disparity between the standard and the actual language that people actually speak, will grow greater and greater over time. And then if you're creating a standard for a large dialect region, the effect is even more exaggerated. So the standard is actually highly artificial--just through the process of standardization, you are artificially creating a language that no one actually speaks natively.
