This is based on the fact that it's impossible for you to win with the material that you had left.
Opponent out of time = remise

True, but it's also a time based game. Does chess.com make this rule or is there a kind of 'official chess lawbook'?

In both FIDE and USCF rules and on this site, in the case of a timeout by one player, the other must have "sufficient mating material" in order to win on time.
If you only have a king you fail this test and the result is a draw. There are subtle differences between FIDE; USCF; and this site's implementation of the rules, but a sole king can never win a game under any circumstances

Clear answer. Now I can go to bed without having troughts of destroying our planet out of sadness ;-)
What kind of rule is this based on?
Me only having king left and 20 minutes on the clock. Not check(mate).
Opponent: many pieces on the board but no time left and 'lost' by time out.
Game result: remise
