You know the fonts on our roads are standardized? And a lot of other official documents?
Designing a font that will be public domain forever costs next to nothing. It's a one-time cost that pays dividends into the future and that will probably outlive us.
The government would create something standard and accessible, and anyone could use it. No encumbered licensing.
I think companies refreshing design systems is a waste of money, but the government doing it is actually incredibly prudent.
