So what's your point? Spend more on a project that is complete but not up to your standard?

Or Extend the mission to something novel? Some how without ballooning the project?

Neither is possible in the slightest.

For what it's worth the Apollo program adjusted for inflation is pushing 200bn USD compared to Artemis 100bn.

The Artemis programme is far safer than the Apollo program in terms of risk, Apollo sampled a much flatter high risk curve just 7 times.

Bottom line let the Astronauts decide what they consider safe enough they're very smart people and deserve to be allowed to give informed consent.
