In the county where I live (not the USA).
You can conduct business (as a hobby, on a small scale) without setting up a proper business entity.
But if you set up a business, the director name and place of business is publicly available.
OG is not small scale. He has sold more coins than most people sell in a lifetime on their hobby store.
If OG was collecting taxes, he would have had to send his tax/business number to everyone he shipped to. He doesn't have one, and has never paid taxes. :/
