Why not focus on reengineering our political and economic systems and their inefficient built in contradictions, like optimizing for consumption?
Things used to be built to last. Planned obsolescence coupled with a human drive to consume needlessly are completely unnecessary to happiness, but decades of propaganda have convinced us otherwise. People don't need to keep driving to their fake jobs, etc.
It's not really extra physical goods that are the issue (e.g. that arm chair made from farmed wood going to landfill), it's the pollution required to create them or the improper disposal of them.
Some cast iron statues made using solar power as an energy source aren't a relevant climate issue.
As such, the proper response is a CO2 tax and proper landfill practices.
