Because a gear emulator, would totally defeat their purpose.
Cvts strength lies in:
Cheap,
Lightweight,
Simple,
And keeping the car in optimum balance of acceleration and MPG when needed.
Cheap cvts just read their gearing from the position of the accelerator pedal.
More expensive ones, count in load as well.
The most efficient CVT, keeps RPM static, when acceleration and load is static, even if the car is accelerating, and keeps it as low as possible when cruising.
A CVT using gear shifts defeats this purpose as it jumps to different RPM ranges, which is what you don't want power, or mpg wise.
