After a certain point that's true but I think you miss the point of the parent. There are many, many hungry people in the world, many people without shelter and further millions who have no access to healthcare education or even clean water. These are not subjective needs.
Those people are in that position inspite of the fact that we could, with the wealth we have, feed, house and provide health care and education for each and every one of them.
I don’t think this is really true, part of the problem is that the wealth that you think could be allocated to this problem was only generated by incentivizing people to build it with compensation, if you turned around and took it away from the people who built it and gave it to people who did not build it, you would disincentivize creation of more wealth, and the wealth you reappropriated would deteriorate, because you neglected to create an incentive and maintenance infrastructure to keep it working. This is exactly what happened when we tried this, starting with poor people in our own communities.
Public housing projects and welfare programs are money sinks that are notoriously counterproductive at meeting their stated needs; and we can’t get people to consider the structural imbalances that result because the need for these programs is an article of faith and among the believers the only acceptable reasons for their failure are “people who don’t agree with the program” and “lack of funding.”
There is a lot of hubris in saying we’re pretty much maxed out now, thanks and time to stop. I’d suggest instead we need to make smart choices, and that usually smart answers are not found at the far extremities. This “we have all we need” bit reminds me of scientists saying physics was over in the 19th century, combined with a bit of Thomas Malthus in such a way that we all die unless we halt innovation. It reminds me of that, but I’d be overstepping to put those words in your mouth. After all human intention has endless range to match the rest.
