More accurate analogy: he stands on fifth Avenue pointing finger guns and saying "Pew Pew". Still swooning, are you?
Monday: Trump points his finger guns and says "Pew Pew".
Tuessday: A man who had finger guns pointed at him goes into a bank and tries to open an account.
"I'm sorry sir, I can't open an account for you. Our records indicate you're dead"
"What do you mean?"
"It says here that our president shot you yesterday"
"Don't you go by medical records or coroner's reports or something"
'No sir, with all of the lying doctors and coroners have been doing about the China virus, we find it's best just to ignore them and listen to the President"
"But I'm standing here right in front of you!"
'Sir, we wouldn't be a Trump supporting bank if we were amenable to recognizing facts right in front of us. I'm afraid there's nothing we can do"
The position that there is nothing to worry about rests on the faith that there is an invisible hard line over which supporters won't follow Trump, we just haven't hit it yet. And that his power will magically dissipate when the grown-ups officially call the election. Both would be nice, but neither is quite guaranteed.
Given that doctors are reporting people dying on ventilators just after raving that coronavirus is a liberal hoax to hurt the president, I'm hesitant to count on either.
I think you're also either viewing the attempt as more binary than it really is. Either he is unambiguously the president on Jan 20th or nothing. As I said before, if states or even large groups of people refuse to recognize the newly sworn in executive, that can create serious problems. It's still a usurping of power even if it doesn't happen 100%.
I would LIKE to be as satisfied as you that people who've been denying reality for four years will suddenly accept it, but I don't think that outcome is a lock.
