Now, the outrageous claim in Buddhadasa's interpretation is that all conditions are of momentary nature and he makes no distinction between spontaneous and more permanent ones. He states that all twelve nidanas arise in a moment of dukkha. This is a bit like claiming that the wall comes into existence momentarily as the ball makes contact with it, or that the racket comes into existence only when it plays the ball. Just not very intuitive...

The man here is not expressing intuitive wisdom or vipassana & again projecting his mind state upon Buddhadasa.

These are matters of insight or spiritual experience. They are not matters of philosophy. They are known by meditation (although scriptures can explain them).
