Mileage run during operational meltdown

Thanks to a question by GregL, the ethics of taking flights just for the purpose of earning mileage during a time of massive disruption (eg American Airlines grounding of their MD-80/88 fleet) are being debated here.  Would you do it?  Think of the miles and possibly bump vouchers.  Think again of the fellow travellers who are stranded somewhere.  What would you do and why?
