Supposing I've made peace with the main gist of this: Cut living expenses to a point where you can work ¼ or so of the time most of us spend working by living somewhere cheap and not being so materialistic.
The missing piece here is social connections. Family and friends. If I could take my in-laws and my 2 best friends and their families with me, I'd sign up to move to a rural place like this tomorrow. But it's impractical for nearly everyone in the whole country to make such a thing happen. This limits its appeal. This place is 90 minutes or so from the Montreal airport, which is actually not bad for rural places, but flights are not cheap, certainly not accessible on the budget described here, so for you to have contact with anyone outside this town, they're likely going to have to drop about $500 per person, per visit, and will be staying at the Super 8 since you probably don't have a guest room). So, implied but not acknowledged in this piece is the assumption that you are almost definitely going to only see your family and friends a few more times (maybe once a year each, if you're super lucky) for the rest of your life.
And unlike questions of money; food, entertainment, family and friends aren't fungible. You can start over and hope to make new friends out there, but you can't replace people. This is what would make this life untenable to me, and I'm not even all that extraverted.
