When to use a resistor with an LED (and why)

I'm just a bit puzzled then, why the resistors are needed at all? If we are switching fast enough, the human eye can not tell the difference.

Driving an LED with or without a resistor

And it can't be allowed to heat up the LED's heatsink because that raises LED die temp.
