All back of envelope here just to get a rough order of magnitude:
Starship needs 10kg (0.5mcf) of methane and 36kg of oxygen per kg to orbit. The oxygen takes 22kWh to liquefy or about (0.16mcf to generate that onsite). So 0.66mcf/kg to orbit and 66,000mcf from to fully fuel.
That is the daily gas usage of a midisze city, say 200k population, per launch.
