As a libertarian, I don't like democracy because libertarians always lose.
But even if we have democracy, there is no reason to use EVMs. Pen, paper, voting booth and ballot box is superior technology because it's so simple. Traditional voting can be done even in really bad situations when there is no electricity.
EVM/blockchain voting is not cheap. Developing a reliable system will cost way more than pens and papers do. Traditional voting is much more cheaper and truly efficient.
EVM/blockchain voting will be so difficult to understand that average citizens can't comprehend how it really works, which means that they can't be sure if the election was fair. If there is any suspicion that the election was tampered, democracy loses it's legitimacy.
If there is a provable and easy way to check afterwards that the vote has been recorded as intended, it will create markets for vote buying. If there's not, then there is no way to know if blockchain voting was done fairly. Anonymous voting is impossible with electronic solutions.
And you have to also understand how bad the computer security is currently. It's not only software but also hardware. It's really, really hard to find a device that couldn't be compromized by hackers or intelligence agencies. Most of the devices that citizens own can be hacked. If those devices are used to vote, it will be possible to tamper the results of elections.
