Remember, endowed rights exist regardless of government.
Bestowed privileges, mistakenly called rights, only exist because of government.
If you have to ask for permission from government, it's probably not an endowed right.
As to the belief that one must participate in FICA :
“The Social Security Act does not require an individual to have a Social Security Number (SSN) to live and work within the United States, nor does it require an SSN simply for the purpose of having one...”

You may stand on your religious beliefs and refuse participation in FICA.
FICA was and is a vile "tax and bribe" scam. It is the foundation of "voluntary" servitude to the collective State. If you believe it is a "good thing" for government to TAKE from one to GIVE to another, you're advocating compulsory charity and slavery.
Very unAmerican.
