The Tor Browser should be illegal

No one can convince me that there is any reason why Tor should be allowed to exist. There are only three reasons I can see why people use it

• Scams, such as stealing accounts, credit cards, and other personal information
• Buying drugs, weapons, and other illegal things
• And worst of all, child pornography

No one can convince me that there are any other real uses for that browser. When people bring up "reasons" like privacy, it just feels like they are making up excuses
