I didn't expect such an extensive reply tbh. My writing skill doesn't compare to yours, but I kind of feel compelled to answer.

The initial thought was that it's "inhumane" to work for a living. I agree with you on most points that you brought up, but they don't really support this idea.(imo)

Our bodies and minds didn't evolve to be able to support our current lifestyle (or workstyle, rather, since it can hardly be called life) without breaking down.

That much is certainly true, and thus we haven't really come far from our ancestors. We have evolved as social creatures, where it was essential for everyone to contribute to a society to ensure mutual survival. It's wired in our brains, as we naturally like those who help us and dislike selfish individuals.

That leaves us precious little time to actually live our life. To enjoy ourselves. To share with our loved ones.

This is true as well, but closer to wishful thinking. We have been able to even entertain this thought only for a small fraction of human history. This is not inherently natural, but more of a perk of human progress.

it's also a fact that we're producing much more resources than we'd need to be able to comfortably sustain every person on the planet

Who is "we" in this case? It's certainly made possible by millions of people working these jobs. And not only agricultural, because this efficiency couldn't be achieved without the modern economy, science etc.

Look, I agree with what you're saying. It's just that saying "having to work is bad, unnatural, inhumane, monstrous" is a little bit over the top, that's all. Anyway, thank you for taking your time to explain your point. I appreciate it.
