You mean like communism? Because that doesn't work very well.
Or do you mean, we stop worrying about anything not related needs. We give up all wants, and just focus on food, water, shelter, etc. In that case I do think boredom would get the better of us. Animals of intelligence, such as parrots, if left in a cage with nothing to do eventually start going crazy and can literally die from boredom.
Modern technology makes survival for the average person very simple, all needs can be met in a very short amount of time. That leaves lots of downtime, especially if everyone in a non need business started to work on needs, the needs for everyone in the city would easily be met very quickly. Not to mention the fact that it would be hard to get everyone to cooperate and do their fair share.
We would have to break up into smaller communities and start living like the Amish.
