I consider it more so authoritarian in this context due to the expectations of those demanding it.
Joke candidates/blank ballots would not stand with them. Part of voting is being able to withhold your vote, to utilize your vote as leverage to ensure your representatives work for you, and that's a big freedom that's would be stripped away here. You're right that it probably wouldn't change much though. You'd potentially do more damage by having uninformed voters who wouldn't otherwise show up submitting ballots.
You summed up most of my feelings rather nicely though.
Personally, I don't believe the moderates truly hate Trump as much as they say they do. In fact, they appreciate him. He is the perfect looming threat that they can use to coerce us into voting for them without them having to compensate or do any meaningful work towards addressing voter's concerns.
Either that, or they are genuinely tone-deaf and out of touch. Take your pick I suppose.
