You don't think that farming, baking, and building are professions?
I assume they mean that it is all already automated in the utopian society. And I would kinda agree that that would be utopian. But sadly we live in the real world where greed rules pretty much everything, meaning that it will remain an unobtainable dream for (most likely) ever.
There's unfortunately a huge contingent of people who would strongly oppose a utopia where we all could live as equals in comfortable, luxurious lifestyles, where robotics, replicators, AI, and automation took care of everyone's needs and wants.
They oppose the "live as equals" part.
Farming and baking are already very thoroughly automated and their labor force completely proletarianized.
