>billions of people will want to spend a first-worlder's life savings to take more than two years of their life to visit mars, and most of a year of that locked up in a tin can just to get there and back. (it's worse if they don't saty on Mars for the whole synod, because then they have to spend two years in the tin can)

Because those 2.2 years apart are as measured from the same place. The return trip is on a different phase because it's from the other side.
Basically, the choice is either (roughly) 6 months out, 18 month stay, 6 months back, or 6/18 months out, touch boots, then 18/6 months back.

>The reason Apollo was successful and not a massive clusterfuck like most Soviet projects is because NASA took small steps before diving into the deep end.
The problem is, we can go to the moon any time we want, but Mars only lines up for missions every two years. And we really need to get an unmanned mission making fuel before we land humans.
We should be sending up an ISRU fuel mission to Mars at the same time we're on the moon learning how to make holes. Also the moon lets you do remote control missions with minimal lag.

what did he mean by that

It all depends on how much dV you add, and how much you trust your spacecraft. But mostly it depends on the relative positions of Earth and Mars orbits.
