Well, with the Crawford rule in place the live gammonless takepoints range from about 17% to about 26% in a 5 point match (ignoring the easy post-crawford and 2a2a cube actions), which is not that different than for money. A beginner who just treats all scores as if they are money won't be all that far off.
Depends on how far off "all that far off" is? Counterexamples:
