The main problem is that parts of our society still treats social security numbers as off they were passwords. However, they are short, uniquely assigned, and not changeable - which means they are user names (identifiers.) (Same thing with finger prints, BTW.) Meanwhile, designing systems that can uniquely identify consumers/customers/employees/suppliers/students with a generally unique ID world lead to a reduction in error rates and increased efficiency. Security must be solved with told designed for it (state issued signing key/device?)
