The bigger problem in my mind is people getting past the Industrial Age idea that you need a "job" to be a worthwhile human being, and that the nature of said "job" determines your value to society.

I don't really mind if there's lots of crappy poetry and tremendous non-enumerative attention to child rearing and looking after the elderly. I don't mind in the slightest if someone decides they just want to watch TV all day à la "Fahrenheit 451".

But in an abundance economy where the marginal cost of production is essentially nil and money is more useful as a signalling mechanism rather than a store of value, it's the mindset that will be most psychologically dangerous.
