What breaks the enchantment?

[the phantom]

On a perfect road, no accidents would ever happen.

Yeah right. It doesn't matter how perfect the road is. There's always going to be someone who can manage to wreck their car in a spectacular display of lack of conscious thought and utter ineptitude for any activity requiring focus and hand eye coordination.

You could put cars on a track so all drivers had to do was work the pedals, and people would still rear end each other.

Likewise, you could write a "perfect" book, and there would still be people saying things like "I didn't get it", "I couldn't get through it", or "I thought it was boring".

On the other hand, there are some people who, despite imperfect roads with potholes, blind driveways, heavy traffic, patches of ice, and the occasional malfunctioning street light, still manage to never crash. Imperfections can be overcome.

But, of course, perfection can be overcome as well, so a perfect work of art does not guarantee enchantment.
