I think I'd feel better about the suggestion for a manned mission if it talked about 1) what value a human would offer in collecting samples and analyzing data over a robot 2) how that value would compare to mass of air, water, and food as well as life-support systems and radiation shielding; the additional fuel and oxidizer to move the mass of the crew and supporting systems 3) the ethics of sending someone capable of doing this important research to their probable deaths rather than an unmanned mission and 4) the cost-benefit to funding this versus other non-space exploration efforts.

What also gets to me is that clearly people have done this cost-benefit analysis before - people that know a lot more about the topic than me. It lacks humility to ignore their reasoning (see https://spacenews.com/independent-report-concludes-2033-huma...).
