A lot of people are comparing being a pilot to being an engineer, doctor etc. The thing these professions have in common is that they have a professional body that controls the qualifications required and the skills needed to do the job.
Take civil engineers for example. After the initial degree they would then embark on their professional development with the Institution of civil engineers. This would then lead to becoming chartered. The Institution takes an interest in the development of engineers from student level and the engineers take an interest in the Institution and attend regular meetings and lectures about the industry. The ICE would never allow anything like P2F in the civils industry!
The pilot profession does not have anything serious like this that would look after pilots interests. Balpa is the closest thing but is a union not a professional institution.
