It does mean that, but in a situation where people don't know what the productive use is you have no other option.

It's like that famous quote about advertising that says "Half my ad spend is wasted, but I don't know which half". 20% of token use is useful, but as you don't know which 20% it is you have to spend 5x more to get that knowledge.
