Voltage converters are big and not that reliable at the consumer level. Putting the power supply in something replacable is a good thing. Going from 19 to 5 would be an extra conversion step.
Plus, 19v is too low. USB does 48v for the 240W mode. You could use more current, but then you are wasting copper and making connectors bigger and heavier.
I used to not be a fan of negotiation but it seems that it's highly reliable these days, stuff isn't getting fried because of incorrect voltage selection.
