Pragmatically, there's a lot of great reasons to not use your personal address as a business address. I still have unemployment claims and financing offers chasing me for a company I started five years ago and closed four years ago.
For some reason, this doesn't seem to be a problem for me. For over twenty years, I've had a registered fictitious business name, a D&B number, and a registered US trademark tied to my home address. I don't even get junk mail for that.
