To reach this value, you effectively have to score at least 105'226'698'750 points, because all objects present in the main campaign are worth some multiple of 50 points. Killing crabs is probably the fastest way to score unlimited points and yields roughly 100 points per second. This suggests that reaching the maximum score would take approximately 33 years.
And that is why we don't do it.

Or once you die, you should lose the points you gained, with the start of the level/checkpoints saving the score you had at that point of time.

1. A 1up could only be collected once, so it doesn't respawn even when you die
2. Points could be given for clear time like in JJ1
3. All amassed lives could be exchanged for big points at the end of the game
