Few things to address.
Industrialized farming has lead to lower quality, so that point is objectively false.
Farming doesn't require big expensive machines. I run a farm and the biggest equipment I have is a pickup and a Polaris.
Saying people should specialize doesn't negate my points. Today, women are forced to work, used to be able to own a house, have kids, and a car all on a mans salary and its thanks to the money printer. If only 1 person has to work, the other and kids could manage tending a garden for 20 minutes a day, it's not a big deal, but go look at war propaganda from WWII, a little goes a long way and also adds community to your neighborhood.
Regulation and prohibition aren't the answer, govt created this problem, they will not be the ones to fix it. They need to end all agricultural subsidies. Period. Fuck the state.
I general take issue with your initial point that this view I have is too romantic. Go research permaculture, we can live better lives more in tune with nature AND have an advanced society. Having an herb garden or one raised bed or raising chickens or rabbits or even a little pig doesn't take long and gives you control over the quality and sovereignty, gardening like this is basically printing your own money.
