To get this out of the way, we're not talking about the value of any old
starting move.
We're talking about the biggest possible move.

The value of the komi is actually quite mysterious, theoretically speaking.
Its possible to imagine the value beeing zero in a game were the even moves
can allways exactly compensate the odd moves.(I know in go that's not the
case)
The practical answer is that the correct (integer) komi is the value that
gives both players an equal chance at winning.
Judging from professional play, on a 19*19 board 8 is is the most likely
answer, with 7 and 9 in contention.
Another thing to look at is the relation between a 1 stone handicap(first
move) and a 2 stone handicap.
The intuition here is that the 1st stone is half a move, and that a 2 stone
handicap is therefore 3 times as valuable as a 1 stone handicap.
That intuition is probably very close to the truth, but there is some
handwaving involved.
