The problem isn't with the state of this utopia; the true difficulties lie in transition process - when more and more things get automated, but the overall economy still forces you to have an income or starve. The real challenge of our times is how we get from here to there without a huge mess and a lot of suffering in the middle.
Yes, the transition will be an upset, like all transitions are. But what I quoted doesn't talk about the transition to the utopia, it talks about the utopia having been reached and people still needing an income. If people's needs are not being provided for they will need income, presumably by trading their time/effort for a means of exchange (money), but if that is the case, then the utopia has not been achieved.
Nothing happens overnight, and confusing the challenges of the transition with the endgame, or that the challenges that existed during the transition will still exist after the endgame is achieved, presents a position that the endgame isn't worth it because the transition disturbs the status quo.
