The system you propose does not account for shifting expectations. Try getting everybody to agree on what "basic needs" are and you are going to pull your hair out in the process. Once people get used to receiving wealth for free, they will look at those who have more and demand that they be brought up to the same level; slowly but surely. For instance, who are you to say that basic needs don't include travel and rich experiences? There will always have to be some percentage of the population that works in order to keep all these machines programmed and maintained, and you don't want those people to be enslaved by the masses. Everyone should be required to work for what they need, but thanks to automation the amount of time people need to spend working to afford the stuff they need is a lot lower than it used to be.
