Tiredness Police?

I don't think you've given enough thought to the premise of your post. Does it matter WHY a crewmember reports "fatigued" for a work assignment? Why do you single out commuting? Is it okay for a pilot to stay up all night with a sick child then show up for work? Can a young single guy stay out and party all hours (no alcohol of course) and show up with no sleep as long as he lives close to work? The requirement is to report for duty "fit to fly."
What someone does on his own time, off duty, is NO business of yours or the company for whom he works. If you have a problem with someone reporting for work unfit, take THAT issue up with the individual and if necessary, management. DO NOT start pushing for commuting limits for the 99% of us that commute and commute sensibly. With declining pay/benefits/conditions it isn't always practicable to sell up and move for every base change for whatever reason. Its all some guys can do to hang onto a quality of life. Some pilots recognize a job as temporary and moving would be insanity. Mandated maximum commuting times/distances/practices would adversely affect a LOT of people.
I don't know where you live, where you work or what your circumstances might be, but in this environment none of our careers/positions/situations are 100% safe for the next 40 years. You might be driving a few hours to your next base for your next company in a few years. Unless, of course, you'll sell up and move the family whilst you're in training.
