I'm with you on all the bits of your post - except this bit.
Certainly there's a non-linear relationship between the power transferred to whatever is providing the thrust (propeller, impeller, turbine, whatever ...) and the velocity of the airframe - but in level flight the drag and weight vectors are orthogonal and therefore independent?...
