We have flown this experiment on the ISS. It is a chemical process that is over 100 years old and is well understood.
It’s also the only way to lift any significant mass off of mars, because as you said we have no manufacturing or refueling there. So the rocket must refuel itself.
It then follows that if Mars is the next major target of exploration, and methane is cheap and abundant, why not get started now? The alternative is to spend a decade qualifying an engine for human space flight after the green light for a crewed mission.
Alright cool but we’ve never used these rockets anywhere other than earth. Their development for future use isn’t an excuse to use them over other types currently.
Also, Mars has lower gravity and little to no atmosphere, there are definitely other ways in that pointless hypothetical.
