The key here is (emphasis added):

I'll work a 9-5 if it means I can afford... ...fair quality food

I know you mention your privilege, and I'm glad you're in the position you're in where your job gives you the means and you live where you have access to a variety of good quality food. (I'm not glad the job makes you miserable.)

For so many, that's just not the case. We can't afford it, or if we can, we're not just working a 9-5, we're working two or more jobs, 10 or more hours a day, and shitty hours, more than five days a week, living in food deserts where food quality is terrible, and on and on.

Now, I agree with you. I'd be perfectly happy working my main job (I work two), if it meant I could afford to live my life without the constant stress of trying to afford to just exist.

Compare that to hunter gatherer lifestyle, where they worked to hunt/gather/shelter/etc themselves for 20ish hours a week and had significantly more leisure time and less stress.

Given the choice between the two, I'd live the hunter gatherer lifestyle rather than working 50+ hours a week as a wage slave to barely keep my head above water. And I know that's not all daisies and rainbows either, but fuck capitalism and this construct we're currently living in.
