Is it? Because at the very least, modern life involves the mass production of plastics, mining of various minerals, and the use of copious amounts of energy. That last one is only kind of solved (as long as everything works and nothing breaks), but I have yet to see any convincing evidence that there is any feasible substitute for the first two.
The solution to the first two is reuse. With enough energy, some form of recycling of becomes feasible for pretty much anything. No oil? Just make plastic from atmospheric CO2!
Is it a solution if the masses refuse to trade cheap convenience for more expensive and burdensome products/processes? Theoretically yes, but realistically no.
