The woman who made that post on reddit didn't have a reason to fear that particular tech or she would have said so. She just didn't want a male tech in her home. I used it as an example because things like feeling scared when a man is biking behind you, or being tense during your uber ride, are difficult to quantify. Delaying medical equipment for months because you are so afraid of an incredibly unlikely scenario, on the other hand, is a very concrete example of harm.

I support giving practical advice in these situations, like dropping a mention of a non-existent husband or calling a friend; reasonable measures that does not impinge on the woman's ability to get medical care. But posts like yours are exactly what I was criticising. Fear mongering, validating women making bad decisions that harm them, appealing to emotion and ignoring the facts. After I read your initial post I was second guessing myself: Are the statistics way worse than I thought? Are women being attacked by people who visit their homes (to perform trades and services) constantly after all?

Of course the answer is no. And after all your fear mongering, heavily implying that having tradesmen over is a huge risk factor for rape and violence, it turns out you have benefited plenty from taking these "huge risks" yourself.

So to answer your question: That woman, and many others like her, had no reason to feel unsafe and uncomfortable in her own home, so she doesn't need to go anywhere.
