Earlier quoted context omitted.
And this sounds like the opinion of someone who has spent literally zero time investigating how universal the consensus is among voting security professionals about how paper is still the best, most reliable, most secure technology with which to run elections.
In-person voter fraud isn't that difficult, and especially in Washington people get packets in the mail they can vote with by returning in the mail which would be pretty easy for someone to go swiping from mailboxes. Verifying identity online is not an impossible challenge and we can't just avoid improving anything forever.
The voting period in Washington is 18 days. So someone would have to either be constantly looking through my mail for the better part of three weeks, or have the best luck when it comes to predicting when I would actually send it out, and that's if they got the correct mailbox and I didn't, say, go to a post office or the ballot dropoff boxes. It would be hard to do even for an individual, and much harder to scale up.
