No election and Trump is still president in 2021?

Let's for the sake of argument theorise that the November 3 presidential election in the United States of America does NOT take place. As Politico brilliantly points out today, if there is no election Trump still has to leave on January 20 2021 because under the constitution he has to leave office after he has completed his four-year term on January 20 2021 UNLESS he is reelected to serve another four years. So, if there is no election in November, he still has to leave office. Politico goes on about who might take over under the rules and comes to the conclusion it would probably be Joe Biden in a temporary capacity until an election IS held. There are all kinds of complicated reasons for this, not the least being that the Senate will no longer be controlled by the Republicans after January 3 because they would no longer be registered members of the Senate until they also get reelected. But let's look at it another way. Let's say Trump makes a proclamation on, say, October 21, that he has taken legal guidance and for the safety of the nation and for the future of democracy and justice in the US, he has decided that it is in the best interests of the country that he remains as president until the pandemic is finally washed away, and that, therefore, he will continue to rule from the White House until a special committee of Congress comes to a conclusion that the pandemic no longer threatens the American people and a proper election can take place in, say, six months, leaving time for a full-throated campaign by both sides. I can see Trump doing exactly that. It would be a sacrifice on his part, a sacrifice for the nation. America First, time for personal sacrifice by the president himself. It might just work. It wouldn't be constitutional but times are unique and unique times call for unprecedented action. I could write the script. As of today nobody supports any suggestion of delaying the election, not the Republican party hierarchy, definitely not the Democrats and not by anyone who has any knowledge of the constitution. But desperate measures for desperate times. This story floated in a Tweet by the Man Himself earlier this week is not by any means the last we have heard of the option to delay the election. No, sir!
