We keep automating away jobs. People want/need work, mostly for money, but also because want to feel they are doing something and part of something. So I don't take it as a given that less free time and more human effort is objectively a bad thing. It really depends on the person and whether they feel a sense of accomplishment in their work.
As for death and accidents, that's somewhat addressed by my typo fix.

The thing about the current economic system is that it's the current economic system. It can change, in small ways and big ways, but I'm not not sure it will (even if we're probably in the absolute best time to try out UBI we'll see in our lifetimes, and it will be a shame if/when it passes us by in that respect, even if it means life is much better overall).
This is your brain on capitalism. :p
More seriously: more jobs, more human effort, more accidents and injuries and death, less free time... this is objectively a bad thing. It's only from the lens of the current economic system that it becomes a positive thing, which speaks volumes in itself.
