I think there is a bit of hypocrisy going on here.
As pilots we are all very quick to criticise airline management / accountants, the CAA, the FAA etc for failing to take measures to enhance safety
but
when there is any call to restrict long time / distance commuting immediately pre-flight the immediate response is 'not fair, shouldn't interfere' etc.
Whilst it might be hard to PROVE that long commutes cause fatigue, it certainly cannot be argued that they in any way improve safety.
