I don't like your answer. I intend to join up with a crew when I find one I like, but I'm not going to join up with people who annoy me, so that may take a while. People shouldn't be forced to join an uber crew just to get a spot to claim. What happens in 2 months when 4 friends decide to start playing the game? They can't have a crew because the only way to have land is join a mega crew who got here in the first 3 days? In the end, nobody who didn't get here, avoid all the bugs and issues, and get out and claim entire regions of the map will be able to have a crew. We'll have 3 crews per server and if you don't like it, tough. That's your answer?
Also, I agree with you partly on stealing. More things ought to be able to have locks on them. But if there's a way to lock up your stuff, and you don't, I don't see many issues with stealing. There's a game mechanic to protect your stuff, you just need to use it. That business of overloading people's ships is griefing. There's way too many ways to grief in this game. They need to shut those down.
