Mars costs the same as the Moon to reach and return from (delta-V) and is a much easier environment to stay in, even over as short a period as a month. Mars makes much more sense than the Moon, which has little of interest and isn’t a stepping stone to anywhere.

If you stay out of gravity wells, traveling anywhere in space is the same cost, minus the non-trivial life support issues, which only come into play on a trip to Mars and back.

Humanity has gotten there before Mars for the precise reason that it is a stepping stone.

None of what you posted is factually true and, in good faith, I have to wonder why you might believe these things.
