This is covered in the discussion in different ways and from different angles, but okay, let's define "perfect" for the discussion then: A picture representing the actual conditions of the situation in the most realistic and technically optimal way possible.
I'm not sure there can be such a thing as perfection re: such as you use as an example. Movement and feeling could be considered a more realistic representation of that moment than something frozen at a high shutter speed. One's definition of realistic and technically optimal can be very broad.
Following that, who's to say that moments in time *need* to be frozen and can't be allowed to flow in time ?
