Stupid Bussiness/ Occupational licences

Why does someone need a business license? In a simple sense you don't. I ran a lemonade stand as a kid during yard sales like every other kid on my street. We also did it together. We had a little cup and charged 25 cents for a cup of lemonade. We didn't need a license. I never even thought of it back then. And why would I? Because I was a stupid kid? No, because it makes no sense!

Why does my friend Don pay 25-50 dollars every year or couple years to renew his license to cut hair? Because the government will come into his barber shop and forcibly remove him from cutting hair. Not because he can't cut hair anymore. This isn't a certification to drive out bad hair cutters. Supply and demand would handle that anyway. It is to protect businesses who have an interest in people paying for teaching in cutting hair. This is a subtopic which stems from rights and privileges. Don's right has been violated by the government by requiring him to obtain a license. He is getting the privilege to do business by the government. Don is a slave. Wait! What about the 13th amendment?
