Oh that's laughable. Why don't you pick a number? I actually value my time higher as does my employer, but go ahead use $20/hr. So 10 days* 8hrs/day*$20/hr=$1600. Still cheaper with propane. Why would collecting and cutting be cost free but for my time? Is the tractor, winch, splitter, chainsaws, chainsaw chains, gas, oil, bar and chain oil, pulp hooks, the land, etc cost free? That's more expense than my time would be even if I amortize it out. If I include all that then obviously propane is cheaper than wood by an order of magnitude. Yet you want to hand wave that away.

I gave you an example of how cutting wood resulted in breaking the tractor and causing a $3000 repair. You ignore it. That adds to the expense.

Let me guess, you've never cut wood.

Additionally putting wood in the stove is an activity specific to wood. You don't do anything of the sort with propane. Why would you not include it when comparing the two.
