The issue is in your statement: price increases to no limit. One day, though, we won't be able to afford it. You'd be surprised how close we might be from that day...

We already have early warning on the oil: conventional oil production is on a plateau since 2008, and non-conventional might peak in 5--15 years. Without cheap oil, globalization dies. It heavily relies on cheap transportation worldwide. Without globalization, either we're prepared or we collapse!

Right now, not a single country gets prepared.

Exactly because the reasoning you have: modern economy is still based on a hypothesis made at the beginning of the industrial revolution "assume infinite resources", and when you run out, it's just because you don't put enough money to extract more.

We've buried most of what we produced. Yet miners go after ppm or ppb metal levels in rocks rather than just dig out waste and extract metals from them. There is a reason.
