Forgetting your hypothetical players for a moment since they seem to show that speed increases OBP which is not really what we are bickering, where I agree with you is
His speed is only valuable if he's able to use it. He's only able to use it when he's on base. The value of speed is directly tied to OBP and in a more loose way, the value of OBP is tied to speed.
It isn't that you can only have discipline if you have speed or vice versa, it's that the value of each is tied to the other.
But I really only agree with that in the sense that the value of any skill a MLB player has is tied to his possesion of any other skill, so basically in the biggest generality I can think of.
Anyway, this is a worthless arguement and I guess we can stop it now because it isn't going anywhere.
