Why is it more resource intensive?
It's far more intensive of a much more limited resource: user happiness.
Normal users tend to find hexadecimal frustrating:
"It's a *number*? But it uses A through F."
This is something that only experience can fix.
"I don't understand. Why do I need the long ID?"
This is something the FAQ should explain :)
"Wait, now I need to use the *entire* fingerprint?"
Ditto.
"You can't be serious: I need to give a 40-character serial number
whenever I need to identify a key?"
I'm not sure users care much how many characters they are copying and
pasting.
"What do you *mean*, future keys will be expanding to 64 characters?!"
... In all this discussion about what's mathematically optimal, I'm
dejected to see how little we're talking about human factors.
... you might note that in my recent response I did mention a very
important human factor. Consistent advice (always use the complete
fingerprint to identify a key) is MUCH easier for users to remember than
trying to teach them when they need it, and when they don't.
