At least a commuter can sleep uninterrupted each night while he is away from home. How many non-commuting fathers and mothers can say that?
If commuting is done in your own time and out of your own free will, FTL's should be totally irrelevant. What's next, FTL's telling me I can't bring my children to school in the morning? FTL's telling me I can't go to a party at night? FTL's telling me that I cannot do my morning exercise run before a flight?
After years of commuting I can honestly say it was of no consequence to my performance at work. I can't say that of my family life..
