> efficiency we gain is largely offset by the rebound effect in our current system of production, i.e the GDP grows faster than the ressource intensity can catch up with

We agree on this. But nothing requires the base resource load to increase. That's my point.

Blaming capitalism for our ecological problem is a cop out. It makes it sound like we have to re-engineer our civilization to escape resource over-use. We don't. The changes are simpler. But making it look like our entire financial system has to be rebooted to effect real change helps punt the issue.
