What's wrong with an amendment? I don't want to live in a world where I have to wear a face mask to get some privacy. And they will probably soon not even need faces but recognize you from your height and the way you walk.
Nothing, in theory, but I don't think any amendment can get enough legislature votes to pass and be ratified right now, and the Powers That Be are absolutely terrified of what might come out of a Constitutional Convention. Anything could happen: gun control, equal rights for women, gay marriage, abortion rights, a requirement that presidents must divest all businesses and show tax returns prior to inauguration, right to strong encryption without back doors or key escrow, technology privacy and personal data ownership... anything.
So then we'll need masks and privacy-enhancing shoes.
