re: #16 Indy GOP Refugee

I fly a cellphone camera to take pictures of my truck for sale and I need a license?

That’s not really commercial use under most law that I’m aware of, anymore than occasionally selling your unwanted stuff on Ebay requires you to get a business license. Commercial activity that rises to the level of regulatory oversight is almost always defined as a pattern of activity. So, unless you’re operating as a car broker, deducting operating expenses from your taxes and plan to attempt to demonstrate a profit motive to the IRS if audited, this is a weak example.
