I think you are making a strawman of the position. Nobody thinks we will be able to just move to Mars in our lifetime. Some people think it is important to spr

  There is no singular "the position", there are multiple people with different positions. Some just want to see humanity become a multi-planetary species this millennium, which is a perfectly sensible goal. Others imagine going to mars as a solution to climate change.

      Unless you ship all the fuel you need to have on Mars while you are there and to get back (expensive), you'd need some technology to capture CO2 from the Martian atmosphere and combine it with hydrogen (from electrolysis) to make methane. But once you have that capture technology working there, it doesn't seem like there would be a problem with running that technology on Earth. If it were possible to capture CO2 directly from the air (DAC), you'd be cutting down the amount of CO2 in the atmosphere that is only there because we burn fossile fuels.
