Do you have an office? My working space at home is a small corner of the living room, a few feet from the kitchen and dining room. There is no better space.

Also, does your wife also work? I just can’t fathom how it isn’t distracting. My kids are two and five, so someone pretty much always has to be watching the two year old. You can’t fully focus on something while watching them. Even my daughter, who is five and can play by herself, is going to need something multiple times an hour; food, a different toy, to go to the bathroom, help getting something, etc.

That's lovely for you. I too have an ideal work from home scenario. But I'm not everybody, and my experience is not representative of all scenarios. There are a lot of people who feel less productive at home for a variety of reasons that don't fall into your artificial bucket of pathological disruptors.
