I think you are definitely on point with your analysis about agrarian idealism. I’ve seen this arguement in men’s ministries that since the industrial revolution men stopped taking their kids to work, there became a vacuum in the home, and then with both WWI and WWII the vacuum became magnified by men disassociated with their families and reality.
I think part of the problem is, even if it’s not intended, as we seek high ground and affirmation of God’s specific revelation regarding fatherhood and womanhood, in God’s general revelation by and through His creation, that ground will always be tainted by the fall.
In other words, though it may be true that God’s creation purposes and affirms what God has said, we are stuck with the problem and effect of sin that twists and distorts everything.
For this reason I think we should be fairly cautious with how we seek to defend biblical principles from nature, or history, or society. However, it’s still helpful to see how biblical principles have interacted in history, nature and society. This is the task of administering God’s word to His people.
It’s a reasoning model, are we trying to reason from the general revelation deductively allowing the hearers to judge for themselves the truthfulness of scripture, or are we reasoning inductively about what we are observing in creation through the lense of scripture?
Just my initial reaction, but maybe I’m off topic.
I think the article posted is excellent and helpful in seeing our creation through the lense of scripture.
