These are common enough bit of nonsense slung by the degrowth movement. A 1% economic growth does not at all correspond to 1% increase in resource use. Saying that something can't go on forever is an irrelevant non-argument (just about nothing will 'go on forever'). Even if these had any connection to reality, that still does not suggest steady-state (maybe we'd want to expand and contract based on energy/resource availability?).

In the 70s, the limits movement had measurable arguments - which did not pan out. Apparently their successors response was to renounce all measurement and make an argument about maybe the far far future. If we used that 'logic' in the past we'd still be living in caves.
