Interesting and oh-so-complicated. I'd like to think that when the expedition set off, they left with the idea that these rules would be fairly relaxed since no one knew that they'd ever be back. And if you're setting off to a new galaxy where you don't know what's going to happen, it'd be nice to know that you won't be left to a life alone for the rest of your time. Then, when the SGC regains control (or what they deem as control), perhaps the rules come back into being? It'd make an interesting story.
