Because gas stoves are popular and with that a reason for people to avoid buying houses in gas-free neighbourhoods. People care far more about what heat source they use to cook their food than what is used to heat their house and water. Since the penultimate goal is to get rid of domestic use of natural gas or at least price it out of reach of most people such gas-free neighbourhoods are deemed to be essential to reach this goal. When gas is still available people will want to use it to cook and heat their houses. Banning gas stoves removes the main reason for shunning gas-free neighbourhoods.
