I think he's missing the larger point that what wifely submission looks like, in practice, is largely up to the husband. She's supposed to be in submission to him, not to some bitter rando on the interwebs.

For a lot of men, their wife is their greatest confident and the person they trust most, so removing women from public life actually hurts those men. Wives are often business partners or stewards, after all. Or she helps him get business contacts or he uses her income to support his investments or business. Some local farmers have wives with day jobs because those jobs come along with family health-care plans, for example, and they can take out loans against that income to purchase machinery, etc.

If you hide all wives in the house, you take away his greatest economic asset.
