Well, that's the question facing us, in the large: Do we create artificial scarcity to keep our bullshit going? Or do we, as a species, learn to relax and stop effing with each other?
We had to hit each other with sharp bits of metal for a long time. We don't have to do that anymore. Do we notice or not?
Bucky Fuller pointed out that, in terms of our technical ability, post-scarcity arrived in the seventies. We can call it with the invention of the microprocessor. (We don't need to postulate fusion, as there is already a serviceable fusion reactor available nearby: it's that thing in the sky that burns your eyes when you look at it.)
Let me repeat that because it bears emphasis: We are already in a post-scarcity condition.
Put another way, all our problems now are psychological. Which is kind of what you were saying, or not?
In some sense, the Internet is a basic need because it acts as a more efficient way of filling people's other needs than what preceded it: the need for social interaction, for entertainment, the need to learn more about the world...
Here's a very simple example. We can make a very strong argument that we've reached a very high mark on safety. We live in a society that's safer now than ever before. Yet we are constantly scared that the world will come to an end. Politicians and the media have made sure we have something to be scared of. Do all people feel safe? No, yet by all statistics we live in a very safe society.
Another one, internet access. Forty years ago, if anyone even mentioned that it needs to be a basic need they would have been laugh at with no mercy. Today, it's not such a ridiculous thought.
You say these are really wants. Yes to some but wants are so strong to some(many) that they become basic needs. How many times have you heard some one say,"I need my coffee." Really, coffee is a need?
Given this what does post-scarcity really mean?
We can define a set of basic needs now but over time they will change and they will grow.
