Bit late replying, but another couple of points:

If a class of resource is cheap and abundant, evil dictators/1%ers don't really have much motivation to prevent people accessing those things, unless they feel it somehow undermines their control.

I also think there would be less motivation to become a dictator if you didn't have to fight everyone else for limited resources.

It would also be much harder for the warlord type to motivate others around them to do their bidding if those others are well fed/clothed/housed.

For as long as the world population continues to increase, land will continue to become more scarce and expensive as a result. Land is scarce even in the so-called utopia depicted in Star Trek. We may reach a point where everybody has an apartment and unlimited food, clean water, medical care, and cheap entertainment (books, TV, video games) but what about access to nature? The ability to go hiking, canoeing, fishing, and camping in a pristine wilderness is rapidly disappearing. At what point do we all end up in a sprawling, dystopian mega-metropolis so commonly depicted in cyberpunk? For many who live in Asia, we are already there.
