Questioning Elon Musk

Space travel is a scam. There is no way to send full tank of fuel into orbit by using just one tank of fuel.

in the real world, a Falcon 9 has a launch payload of 13,150 kg and a takeoff weight of 505,850 kg, which means the mass ratio is about 2.6%.

Rocket mass ejection propulsion technology is the least efficient method of mass acceleration. The boosters only last 3 minutes. How long does the upper stage last?

Even the largest rockets can't travel around the Earth on a flat highway without refueling multiple times, so how do rockets get payloads into orbit or Mars?
