To add to the sibling comment, collecting this wood takes time. I've collected wood the forest service takes down for use in a stove I use but processing all that wood takes time. You bring it home, cut it into small bits, keep it in a dry area to make sure the green wood dries out, and then you meticulously rotate older and newer stock to make sure you use the driest stuff for heating.
If you're living on $432 / month and working 30-40 hours at this cashier job then using your off days to grab and process wood is honestly pretty miserable. There are slums in developing countries with higher standards of living because they can heat their "house" (read: tent or hut) with oil.
I grew up in a 1300sf wood heated house, so I have relevant experience here. It does take time to buck, split, load, unload, and stack the wood. It goes faster if you have a small child (me) to help!
We cut wood for our own use and also sold it, so it didn't require 100% of our time to keep the heat on.
Well, minimum wage in NY state is $15.50/hour. ($432/mo)/($15.50/h) is about 28 hours per month, i.e. 7 hours per week.

He also mentions other forms of employment, like raising rare herbs, so maybe he's got a little homegrown operation going that doesn't take much time.
