Not only is this unnecessarily snarky, but it's wrong for many jurisdictions. In those, you cannot vote absentee unless you are actually going to be absent and unable to make a trip (within reason) to your designated polling place.

Many states will issue an absentee ballot only if you will be out of state on election day or have physical disabilities that will prevent visiting a polling place. Submitting an absentee ballot without meeting those conditions is voter fraud, which is a felony.

Depending on your state it can require an hour drive to a polling place for the 4 hours it is open on a random Thursday to get the ballot and provide a valid reason (doctor's note) why you need an absentee ballot.

Honest question: where is this happening?

Mostly in the South where easy absentee ballots would interfere with the black voter suppression systems.

20 states don't allow absentee ballots unless you have a valid excuse (medial or you'll be out of state).

Some of those require you to appear in-person at the country registrar or before a board of elections to fill out a ballot.

I've done an absentee ballot several times. It's a bit of a pain. If it wasn't so easy for me to vote in person, I might not vote as often.

It is often illegal to vote via absentee ballot if you are physically present in the jurisdiction on the day of the vote.

Many people who followed your advice would be "guilty" of voter fraud.
