I think I stopped worrying when my government job forced me to give up my SSN, fingerprints, full background history, financial info, etc. to gain employment. Once your privacy has been raped at that level and you get an insider view into how disturbingly casual the government is with safeguarding your information it's difficult to get spun up about protecting your identity. The human in the loop for those things that do require your information is always the weakest link, so all the caution and anti-intrusion systems in the world still leave you exposed.
