Some of this is overreach and a blinkered desire to attack her lifestyle though.
I don't think so. This is a woman who imposes significant restrictions on her family's lifestyle, particularly on her husband, because of what is in her case a fairly low risk.
I've said several times I am not seeking to change this woman's lifestyle and if she wishes to live in a state of perma-isolation that is her choice.
But anyone who expects their family and wider networks to fit into this worldview without any negative impact is deluding themself. Why should her husband be obliged to restrict his own life to cater to this? Particularly as she's not in an extremely vulnerable category.
If I told my partner that I was taking a vow of silence and chastity and no longer wished to communicate with him he might, not unreasonably, decide that I had changed the terms of engagement in our relationship. It would be entirely my choice, but I wouldn't blame him if he decided that he didn't want to continue on this basis.
People don't live in a social vacuum. If you choose to live an extreme and highly restrictive lifestyle and to impose it retrospectively on the people who are closest to you, you can expect some of them not to adhere to this.
Some people choosing to live this life seem to want to cherrypick the benefits of social contact with an extremely limited group of people (ie those in their inner circle) but to expect those in the circle to also eschew their wider networks. If you, as a sentient adult, take the decision that you no longer want contact with the vast majority of people in the world, don't expect other people in your inner circle to accept this without question. It's highly disruptive to their lives and they haven't chosen it.
Masking, ventilation and sensible precautions are one thing. Expecting your family to distance from you every time they meet other people other than you is controlling and unreasonable.
