There are several reasons which I have for not disclosing a SSN.
Religious Objection. I believe that the SSN may be the mark of beast mentioned in Revelation 13. Also, participating in Social Security violates several of the 10 Commandments. Also, paying taxes supports genocide, and is in violation of the commandment, “Thou Shalt Not Kill”.
Political Objection. Social Security is by nature a Socialist Program. I am no socialist.
It is voluntary, however, and I no longer wish to volunteer.
I have personally never applied for a SSN. An application was made for me when I was 15 years old. I cannot be held liable for a decision that was made for me when I was an incompetent minor. That number is now inactive has been for over 5 years.
