I do not think such a world is desirable. It would just distort markets. Everyone will charge more for everything, starting with rent.

If you cover the basic needs of "everyone", the number of everyone will just go up and up and up until you can't cover the basic needs anymore. Do you think earth can sustain infinite people? There has to be a mechanism preventing people to increase their number to unsustainable levels. The current world already does a really bad job at that, I don't think we have to make this worse.

I think the most desirable world is one with a build-in pruning process, where only the most adapted people survive, thus preventing the number of humans to reach unsustainable levels, while still progressing to greater heights. After all, if you just put a cap on the number of children people are allowed to have you're just going to stagnate. It's better to have a large pool to select the fittest and prune the rest, resulting in the same number at the end, only with much better quality. Historically, war was such a pruning process. But I don't think it was an especially good one.
