^^ this exactly, so no need to for me to repeat it.
But I will fall back on the p-word again. You can be a professional (as in a noun) in an occupation because you are paid for doing it. Of you can be professional (as in an adjective) in the manner in which you conduct yourself within an occupation, whether you are paid or not. Anybody involved in aviation (in any of its forms) who operates with a disregard to regulations, compliance and such things as licencing are unprofessional.
Period.
"Paperwork" implies such things are mere bureaucracy, which they most certainly are not.
Apologies for labouring the point, but I don't think the waters are remotely muddy here so personally I'd rather the key issues are kept clear of any form of obscuration, however well-intentioned.
