Your boxing match analogy is flawed because an outside element (the referee) steps in to stop the fight between the two opponents.
You can win aside from checkmate too - if the tournament director or an arbiter steps in (same role as the referee) and declares the game over due to a rule violation such as your cell phone going off.
Your boxing analogy also is flawed because the fight is stopped based on concerns about the opponent's health - not because he was punched too many times but is otherwise coherent, lucid and fine
And we'll spend - and waste - all this time and energy because we don't feel like doing the hard work of improving at chess and would rather change the rules to cover up our own failures and inadequacies.
And what failure or inadequacy was Lasker trying cover up. He was world champion when he proposed it.
I think you could make a better argument that the people who changed stalemate from a win to a draw were the ones trying to cover up failure.
