Just going to reply to myself after giving it a little bit more thought…
The problem is scarcity. There aren’t enough resources to go around for everybody, so we have conflict with each other over those resources. If we could use technology to increase the amount of resources available such that there is no more scarcity, we wouldn’t need conflict anymore, and as a consequence there would be no point to having power, and no need for governments.
The big question is: is there a limit to technology which will prevent us from getting enough resources? We’re already using up this planet’s resources and soon we’ll start using the resources of our solar system. Mankind will simply expand to fill this new abundance of resources, because procreation is our nature. Resources will start getting scarce again, meaning we’ll have to venture out into our galaxy. But can we even do so, technologically speaking? The speed of light is finite, so the very laws of nature may mean a never ending scarcity of resources available to us.
You mean artificial scarcity of those resources by, for example, companies charging access fees, as is the case with scientific journals?
I think that problem is still inherently a cause of scarcity. File sharing is cheap enough that it doesn’t have to be scarce, but companies want money, and they’ve figured out a way to make those resources artificially scarce. But if food and shelter and whole bunch of other stuff wasn’t scarce, companies wouldn’t even need to exist. Why work if all resources are readily available for free?
Do note that I’m talking about some Startrek-esque future utopia with basically unlimited availability of electric power, natural resources and automation. Maybe we’ll get that far as a species someday, but for now I guess there’s plenty of scarcity to go around. Pun intended. ;-)
