I can understand why privacy is not an issue for you,with the user name you have you might be from India and born on 1992,and since there are a billion people you might think that people does gets confused because there are a lot of people to find you.  ,the aspect of privacy is not about boasting who you are in the crypto currency world,but to have a control over your life,your personal details,your financial details and your family details must be private,if these details falls in the wrong hands you will get into some real trouble that you cannot even imagine,like identity theft etc.
