> It's a question of economics, energy production, and negative externality.

And we're doing a pretty poor job at solving those problems today, for many people at the lower end of the wealth & income spectrum. What makes you think adding more people will magically fix those issues?

I don't think anyone is arguing that it's technically impossible to fix issues like this and have a much larger population, with everyone housed, clothed, fed, and even more than that, happy. But humans -- especially those with wealth and power -- are a selfish bunch, and we are pretty bad at sharing when the goal is to raise other people up.

I mean, we could ensure that not a single person on Earth went hungry. We could do that today, with our level of food production technology. But we don't, because we don't like the economics of it. We could swallow it and do it anyway, but we refuse to.

The continued comfort and wealth of the haves will always be a priority, at the expense of the have-nots. Eventual post-scarcity increasingly feels like a pipe dream to me.

> So, let say that you have a square kilometer area. If you add a floor of space, congratulation, you just doubled the amount of space in an area.

That's just another way to create inequity. Would suck to live on anything but the top level, without sunlight in your home. Sure, maybe it's possible to get sunlight to everyone's home, but let's not pretend that would actually happen, out of the generosity of every builder's heart.

It's really not a problem of economics. It's entirely a political problem.

Not everybody care for natural sunlight. I certainly don't. Moreover, I see sunlight hitting the roof of my non-solar paneled house as uselessly bouncing and heating things up unnecessarily. Just another resources to be used and transformed into something more our liking.

If you're talking about open space for a sufficient definition of open space floor plan, then it's a question of engineering.
