Why not 400KV to 11KV Step Down Transformer Directly Used in a Transmission System?

The electricity network system mainly works under three major sects- Power Generation, Power Transmission, and Power Distribution.

Why can't we step down 400KV direct to 11KV in a transmission system?

To find the answer to why we cannot use the high-voltage or extra-high voltage step down directly to the distribution level voltage, let us know the transmission and distribution voltage level from the generation station to the user connection point.
