It’s clearly about mocking decentralized home made solutions to problems, and of the people who opt for that approach. It’s an insult to every Amish person on earth and to home mechanics who shy away from garages. It’s also, by far, the most downvoted thing I’ve ever posted so thanks for using your other accounts to hit me for my acidic and savagely inappropriate comment
Growing wheat and grinding it out into flour isn’t something I’ve ever heard anyone take on as a hobby before. Having all that actually cost less (including time) than buying bread would be a huge achievement!
Spoiler :P it definitely took way more time an effort than buying flour from the store and making bread. And the final product was a pretty poor loaf of bread because he couldn't find a way to buy the same type of wheat most farms use and had to settle for "animal feed" quality seeds.
