your analogy works if you were to harvest wood with a steam-engine powered saw, built and delivered by a steam power.
Great. Then let's assume it's harvested and processed by a steam machine, if it helps you understand. So you agree with me, that even with a WROWI (Wood Returned On Wood Invested) of approaching 1, I don't have to have reduced activity. Instead the opposite is true, I make very effort to cut an enormous amount of wood just to get my single cord.
Let's try another example. Without beer you die. So you brew your own beer. The taxman comes and every year he wants some more percentage from your brew. Assuming you can't cheat but have no choice in paying the tax, what would you do? Keep brewing the same amount of beer every year, having less and less for yourself. Or you would go to heroic efforts to brew as much as possible so you get the amount you need after taxes? Clearly as hell your standard of living will drop, as more and more of your time will be devoted to brewing beer, yet you can see that your overall economic activity did not drop. You're 100% busy and employed in brewing beer. Cheers!
Your second assertion, that a replacement industrial/economic infrastructure (run on wood?), is necessarily available is also nonsense. We built our world on oil. It will end without oil.
It was an example, for simplicity of understanding. I thought you owned some wood? And you might be better able to relate the argument at hand to a more tangible asset in your own backyard than to a resource far removed.
The oil age will end when
1. the OIL RETURNED ON OIL INVESTED (OROI) does not provide basic necessities for people (food, shelter, safety, some medical, some cheap entertainment)
2. a sufficient substitute for oil becomes available
You can have full employment and a GDP as large as todays even with $500 oil, albeit at a reduced standard of living, no doubt.
