Decentralized localization of every possible energy generation system (renewables but if we’re dreaming here then the supposedly suppressed Zero Point / radiant / overunity energy systems). Post scarcity abundance levels of all essential items, but mainly food, again through the localized means of production with vertical farm towers if space is a constraint. Free travel to anywhere on the planet and beyond using suppressed anti gravity electrogravitic technology (you said I could dream). Free access to every form of media ever made and knowledge formerly sequestered behind paywalls or otherwise suppressed, and a free and open forum to discuss these things.
But most importantly a new way of thinking that is cooperation based instead of competition based, and a new economic system that renders the profit motive obsolete and money itself much less of a controlling factor in peoples lives (such as a resource based economy like The Venus Project)
