I'm not against currency existing, or people getting paid for their labor. I am against things like medical care being locked away behind a paywall, and the threat of things like homelessness, deprivation of medical care, crushing debt, starvation/freezing, being used to crudgel people into working those unpleasant jobs (often more than one, often with no benefits).
I think in a better society people will still want more than basic survival, and if society needs someone to do unpleasant tasks, it'll still need to make doing those tasks worthwhile.
And to tie it back to the comment I was replying to, I'm skeptical that those unpleasant jobs are enriching the lives of the people doing them, or providing challenges that make them happy when they wouldn't have otherwise been.
