These laws already exist as part of Sarbanes-Oxley but aren't as strict as what you're proposing. Certain public companies are required to implement safeguards that prevent most employees from having access to customer PII(personal identifiable information). Non-public companies don't have to comply with SOX regulations but maybe some of them should be expanded to include large private companies.
