Answer by LvW for Why feedback resistance is high?
In most cases, such a circuit is used as an amplifier vor signal voltages. Thus, it is desirable that the input resistance of the amplifier stage is large in comparison to the source resistance of the...

At first order approximation, you are right in that Rg could be replace by a short and you'd get the same thing, at least in the steady state. However, the dynamics in response to Vdd changes would be...
