Your point is only valid if in fact you had real income generating work you could be doing instead.
True, but I do use this logic to justify having my tractor (and having paid for). In fact, there are a lot jobs that just wouldn't get done without it. It is a huge time saver. Money, I can get more of, eventually, but time, I can't.
I guess by the logic of this thread, I should give up on heating with firewood and wood pellets, and go back to fuel oil. I guess the wood pellets might be break-even vs. the fuel oil, as they don't require that much time, although, I do spend about 20 minutes each weak doing a minor scrape and clean on the burn in the boiler.
As for the firewood, at $90 an hour for my time hauling, cutting, splitting, handling, etc, it is WAY more expensive than the fuel oil
Never mind the fact that, being a desk-bound worker during the week, I enjoy the time spend outside doing these tasks, and that I'm helping saving the planet by burning a carbon-neutral fuel instead of fuel oil/diesel fuel (leaving more of it available to burn in my tractor and truck).
The reality of it is, that yes, while I could spend that time on a 2nd job (that probably wouldn't pay very much), I still have far less money going out of pocket to heat the house. AND, the gov't hasn't yet started taxing me on money that I avoid spending, where a 2nd job, would mean more taxes paid (and wasted by the gov't).
