It's not possible to live a life of modern conveniences, cost and time savings without technology and specialisation.

Youtubers who grow their own farm can only do it because it's their full time job. Or all their time is spent on the farm. Growing food is not easy, and would cost way more home grown.

Not something to romanticise. Nor would going out to the woods help, the carbon footprint would be so much higher than being able to have a expensive house with mega efficient everything.
