This is not about un-ringing the bell. The certification ship sailed ... the electoral vote count sailed .... Pres Biden is indeed the president.
This is about providing "facts" for the people who believe Mr Trump is the son of god ... he won the election. It provides a palpable rationalization in the face of incontrovertible evidence the election was stolen.
Supporting Mr Trump is a religious act of faith. He is the voice crying out in the wilderness. He is their voice. The voice of disenfranchised ignorance and paranoia.
The impact is more powerful than you may think. I have overheard the words "civil war" spoken in hushed tones by these people. If I should ask any of them would they allow a secret partisan recount conducted by the most ardent Biden supporter, they would in loud chorus say no. But if I point out the obvious, they would say it is ok.
