But the problems we had with the last election weren't caused by fraudulent voting. Everyone voted properly, it's just that another country spent some money convincing us to vote the way that they wanted us to. Even if we moved to a direct democracy system and gave everybody unbreakable crypto, it wouldn't stop them from watching TV and sharing junk on social media.

Remember, Trump lost the popular vote. If we had moved to a direct democracy system, assuming as little changes as you say will, he wouldn't be standing in the White House now.

The reason for crypographically secure voting is to stop any form of election-interference that could happen, because that naturally would be the biggest concern from moving to a digital solution.
