ebay business jewelry

Why do not you need a business license to sell their own products on Ebay?
I understand why you would not need to sell personal items like a garage sale internationally. But if you have an eBay shop and sell home crafts such as a home business Part-time (eg, clothing, handmade artwork, jewelry, handmade )…. Why a license is not necessary? I learned a trade license is not necessary to Ebay, so I could be wrong. But if this is true, nobody knows why it is exempt license by going to eBay? I know you always have to declare as income on your taxes extra. But I want to make sure I cover my motivations when it is legal tender with small businesses and Ebay.
It is not necessarily free, it's just that the legislature soon catch up with technology.
