Replace with "the place where you sleep at night" for the general case, in the developed world. (Roof, kitchen, livingroom, bedroom, etc.) Possibly shared with family. The point is, even if you don't own a business, you're going to want a place to live, and you'll have to pay for that anyway so, assuming no other complicating factors, it seems like a smart idea to also consider using that space to work on your new business. Home != house != ownership. Home is where you sleep on a regular basis, where you store your stuff, etc.
I agree with your overall sentiment, but this part... I'd disagree with. Home ownership is not for everybody.
