LUVOIR is, at present, merely hypothetical.
And, no: we won't be living on Mars in a couple of decades. At most, there'll've been a few people visiting Mars for a short time before either (a) coming home, or (b) dying.
We'll no more be living on Mars than we were living on the Moon between 1969 and 1972.

The plan is to take about 100 people at a time to Mars
This isn't 3 astronauts for a few days. We'll need to be reasonably self-sufficient on Mars from day 1, because of the time it takes to get there. We need lots of people to make it work. It's not feasible to keep going back and forth; people will be staying there for many months/years at a time, even the first trip.
