But singling out people, who are trying to make a living — that's not fair and there is no justification for it.
If you want to take a paying passenger then you need a transport pilot license.
That it is so currently is not in itself evidence, that that's, how things ought to be... Why should I need a government's permission to earn money doing, what I am allowed to do for free?
The license is there to (among other things) show that you have that experience.
