> Since there’s not enough reaction mass on earth to bring even a fraction of the human population into orbit Napkin math to disprove this claim: 7,000,000,000 people * 100kg = 700,000,000 tonnes = 7 million launches of starship * 5000t propellant per launch = 35 billion tonnes of propellant (approx 1/4 natural gas, 3/4 oxygen) Annual natural gas consumption in the US is 34 trillion cubic feet, which is about 800,000,000t. So about ten years would be 8 billion tonnes of natural gas (32 billion tonnes of propellant once you add oxygen) So excluding things like keeping your payload alive and breathing, the US generates enough natural gas to launch one tenth of the world population into orbit every year.
