Re: Watch the Texas case
A pre-filled ballot wouldn't reduce wait times to "zero". They are still going to want to check your ID against the voter registration list, and if they dispute it because the poll worker doesn't think you look like your picture or doesn't think the signature on your ballot envelope matches the one on your ID then they have a different set of procedures. Introducing a new procedure like this on election day would be a disaster waiting to happen.
If they really cared about protecting people from coronavirus they'd allow anyone to vote absentee. If they are worried about the security of that process do the drive thru I outline above for GETTING the ballot. That way you have a month or two where you could show up at a designated location for drive thru ID check and ballot issuance. You take the ballot home, then fill it in and mail it at your convenience.
This process also gives you time to rectify any errors in your registration information or whatever that would have prevented you from voting on election day. Which is why republicans would never go along with it, because they are ALWAYS against anything that makes it easier to vote. They want long lines at the polls, mass confusion over inaccurate and outdated registration data, etc. because that's how they limit the black vote.
