I think if you limited it to only sanctioned communications you'd limit this problem quickly (think only .gov email addresses can email it, for instance, and/or other sanctioned domains)

If we wanted to, we should provide two emails to the general public. A restricted communications one following the rules I suggest above, and perhaps a more general purpose one for those who want to use that, with the only requirement that you already signed up for the first one).

I know that's convoluted. It's just one idea of course. I think we could deal with this problem.

Also the gov being the gov, they could just mandate Google provide spam filter protections or something.
