This whole argument is based on a fallacious assumption: it completely overlooks the fact that every economy is based, not simply on currency exchange or freely available information as you suggest, but primarily on NET ENERGY, which is the energy you have left after the energy you invest to get this energy. And the net energy of renewables like wind and solar is very low, even in the negative numbers, when you factor in the embodied energy needed to tap them to begin with. An enormous amount of energy must be invested upfront to build out a wind, solar, and hydro infrastructure to meet the energy demands of a digital economy. Where will that energy come from? Electricity? Hydrogen? Please! Both of these are energy carriers, not energy sources. They both require a huge prior investment of energy to harvest the renewable sources and distribute the resulting energy. And where will that net energy come from? You can't build a windmill from wind energy, nor a solar array from solar energy. These innovations require the building of a global infrastructure to happen at all--driven by--you guessed it--fossil fuels, which are our only existing source of ample net energy. Yet these very fuels are destroying our planet!

So there is a third alternative you have overlooked altogether: relocalization of the economy through regenerative, small-scale agriculture, also known as Permaculture. It won't make anyone rich, but it may allow those of us who plan for it to survive the coming, inevitable collapse and global die-off. Grow gardens, grow community, and grow awareness, if you want a future at all!
