Is there such a thing as a 200hr F/O who doesn't want to be a captain? Surely, if such a person exists, they should be encouraged to see their potential.
The old fashioned dinosaur who is suggesting that it's wrong to want a command are exactly the sort of person who caused TFN for KLM, or any other situation where the grumpy old captain has oppressed the F/O because he didn't deem them to be worthy.
They ought to be ashamed.
