If the "fast-paced, innovative future" includes petulant children stomping around mad because the big, bad government won't let them do whatever they want no matter the consequences to those around them, I'd say governments are more relevant than ever.

Its not the government imposing these restrictions, its your neighbors. If there were no government for them to impose them through, they'd use other institutions, or else just the threat of violence. You can imagine a government-free future all you want, but you're talking about a non-collectivist future, which is absurd.

What exactly would that future look like? Where there is no government, one will appear. People seem to have this incurable efficiency whereby we create rules, regulations, and eventually bureaucracies. Rules, implicit and explicit, manifest whether you like it or not. Authority manifests.

The sad thing is that the US government had much less influence on its citizens 120 years ago than it has today.

It is possible (I believe it's even likely) that humanity will never see such freedom again.
