Bottom line is Bose, although I caught the bug fairly late in life (I'm 30), I love to fly. Why should I accept logic like that just 'cause them's the rules?
Useful VFR flight in northern europe is not a realistic proposition (ie going away for the w/e and stading a fair chance of being able to get home when you want).
You would have to trust me not to put myself in a situation where my arrival before nightfall is borderline, the same way my green (brown?!) PPL licence allows me to take several other people's lives in my hands and fly them off somewhere VFR; and not stray into cloud and kill everyone...
A simple answer would be a stipulation that on a day only IR min fuel endurance = at least the time left before dusk. That way, running out of daylight would be the least of my worries!
