Since the PA46 was designed for the American "a 20,000m hard runway in every town" market, I don't suppose Piper thought the liability was significant. Another 10 seconds with 350-500HP and you will be airborne.
The USA gets significantly more utility out of a plane which cannot do more than a few hundred nm with 4 people, than Europe with its relative scarcity of runways.
Sounds like if you've flown in the US at all, you've never been away from the east coast.
