Yep, a lot of people think it's worth it. I'm with you. Good luck getting the money. One accident will cost years to "improve safety", and people will question if it's really worth it. Keeping humans safe is costly.
I bet we can get the money for better robots. It doesn't even need to come from NASA's budget. The DoD, private industry tax breaks, etc can pay for the research.

If we lose a robot on Mars, not much changes.
