Completely against the idea of having a crew and here are my two cents :
A) Extra spending, for some people restocking a "bigger" ship might be a few pennies but for other it could be a lot of money.Also upon death I would assume the crewmen die.So keeping that in mind people who are constantly in combat situations are going to have tons of spending.
B) Even though it would add more roleplay value, it's still going to be a massive nuisance, also keep in mind the people who just start playing and attempt to participate in trading or mining.Can they really afford such spending?
Conclusion: The use of it does not outweight the hassle.
