Will Kamala Harris become president despite losing to Trump? Will that be right?

While Kamala Harris has conceded defeat in the US elections, a section of Democrats are asking Joe Biden to step down and give the US its first woman President. While Harris is running the administration for all practical purposes, almost acting as the President of the US (POTUS), will it be fair on Americans to thrust upon a candidate who lost the popular vote?
