Coldzera doesn't need to take the risks of those other players, nor does he need to be aggressive. He is the single best player in the world at his role, and at the end of the day that is his job; to fulfill the role required of him.
No other player you mentioned could do Coldzeras role as well as he does. They require freedom, Cold does not.
If he has to bait, he will bait. If he has to get eco frags, he will get eco frags. If he has to let players run into his crosshair, he will do so and everything he does, he will do consistently unlike anyone else.
This is what is required of him. I don't believe he is the best player in every position and in every role, nor do I think he is a player with the highest skill cap.. guys like Niko, s1mple, Shox or Snax definitely have him beat. But no one can do his job like him.. and that is just a statistical fact.
