The kicker is that for most state licenses (varies by state) you need a permit from the TTB (Tax & Trade Bureau). The TTB has a requirement that you own the property (check one for most people - renters may be out of luck) and that it is not zoned residential. (Dual purpose commercial/residential I'm sure would be fine)
So you could brew out of your garage, and get a permit to sell legally. But you need the approval of the TTB first, and I think the FDA. So they would inspect your premises! That right there is the limiting factor for 99% of homebrewers, and thus why they don't take those steps, and it would than be illegal for them to sell. I've seen other threads talk about the legality, or lack thereof, of "trading" to friends for donations back into their equipment, etc. Generally all of that is illegal, but falls more into what should be moral guidelines rather then legal ones.
