I agree with you. People new to knife training need to work with dull edge blades (don't train with soft rubber knives, they are a complete waist of time).
They need to develop an understanding of what a blade is capable of doing (test cutting meat etc, using diffent knife cutting angles, thrusts etc, is a good way of developing this understanding).
Once you have a good feel for blade movement and have stopped catching yourself... and you will... you might choose to move on to a live blade with the edge taped over.
Finally, try a live blade, be prepared for your first self inflicted wound... knives have a strong desire to do their job and will not be happy until they have tasted your blood!.
Its all about gradual progression and a sensible attitude to your training.
Respect the blade, and it will serve you well.
