'Clearly a fool'. Whatever the grey areas might be (FWIW I'll be steering well clear) offering what he himself calls 'Air Taxi' as a PPL (let alone a 65 hour one) certainly isn't grey.
Bizarre really. He must have studied enough Air Law to get through his PPL and this gets drummed into you as a 'Thou Shalt Not'.
So either...
1. He wasn't taught it, in which case what else wasn't he taught that he might need to know
2. He was taught it and forgot it (at 65 hours one would hope it would be fresher in the mind), in which case what else has he forgotten
3. He was taught it and remembers it, but believes it doesn't apply to him, in which case what other laws in aviation don't apply to him ? (Gravity ? Darwin ?)
