The Living Force
Well, the lunar lander weighed 6 tons while Starship weighs about 150 tons, with about half of that for cargo. The Apollo return vehicle that launched from the Moon weighed 2 tons, while Starship would weigh at least 70-80 tons when launching from the Moon. That's a 30-40x difference, while the Apollo rocket was just slightly smaller than the Starship+Booster.Starship hasn't made it to LEO. To get to the moon they say it'll take about twenty Starships.
They did it with a single rocket multiple times back in the '60s, allegedly.
Won't be going to Mars.
And it is supposed to be reusable, as in just fill it up with fuel and you can launch again. The Falcon rockets do show that reusability works, some of them flew over 20 times.
I think in terms of adventure, inspiration and expanding horizons, there is nothing wrong with going to other planets. Especially if it can be done by reducing the cost sufficiently through reusability.
