Chess is defined through the rules, if the rules say it's draw then it is draw
and not a won position.

If you remove the 50 move rule you will see players torturing the opponent for
900 moves in a drawish RN-NN endgame.
They know it is a won position so they won't ever grant a draw, they just can't
figure out how to win it.
Imagine if this is an important game for the world championship, the game will
never end.

That is not the spirit of chess IMO, you need a rules to prevent the game from
continuing forever.
But the solution is simple, if you have a winning advantage then don't trade
into an endgame you can't win in less than 50 moves.

I for example try and avoid the KBN-K endgame because I'm not sure if I can do
it in less than 50 moves.
That is correct spirit of the game IMO, it wouldn't be any fun if I got a
trillion chances to win that endgame, he might as well resign on the spot.
