I really don't know what to tell you. You're literally calling for universities to either break the law or not worry so much about following it, and calling people who do want to be careful about following the law "incompentent and useless".
If you don't see how extreme that is, and how much society would break down if everyone started thinking laws were optional and ought to be ignored when they prevent you from accomplishing your "mission", I just don't know what to tell you.
Just to be clear:
E-mailing a student their grade is not "breaking the law".
Not e-mailing a student their grade is not "being careful about following the law". It is just sheer laziness.
A university may develop a policy of "we don't e-mail grades" for another reason, but FERPA is not a valid reason.
Quite the contrary: society very obviously runs because people ignore policies and laws constantly. That's why following all laws exactly is considered a protest or subversion strategy: malicious compliance.
Like the entire AI industry could only work by completely ignoring copyright law. Basically no software could be written if developers were concientious enough to check for and avoid patents first. Tradesmen ignore safety policies. Doctors ignore limits on hours. People do work on their homes with no permits.
Part of being an adult is exactly knowing which rules are important and which you ignore.
