Hmmm, I do wonder if people on these forums, when they think of single family seasteads, are assuming that “family” means “nuclear family”. I see no reason why an extended family – greatgrandpa, his siblings, and all their descendents – couldn’t set up a seastead, which would technically be a single family seastead, though it could have several dozen people living there….
Now, when I say great grandpa, I’m assuming that the children they are the great grandpa of will be quite young, so you’ll have 3 generations of adults who can actually contribute. I’m saying this because, in this instance, it’s concievable that the oldest member of the family will only be about 70 years old, and fit and healthy enough to be able to help around the seastead (for example, my own grandparents on my mothers side are 68 and 70, I think- and my brother, being 20, is old enough that it’s conceivable that they will be great grandparents soon, within the next decade certainly [my mother was 20, and my dad 25, when they had my brother). So, say you have a few generations of moderately sized families, say an average of 4 children, plus their spouses. That’s 8 people in the oldest generation, plus 24 people in the generation below that, plus 96 below that, plus assorted young children… okay, so under liberal assumptions we’re talking about >130 people. Much more realistically is a community of maybe 50 people, if we’re talking about a society where 3 kinds much more common than 4. This isn’t quite a town, but more than what people usually seem to mean when they say single family seastead, with a natural heirarchy in place. Now, how would things be different?
Well, for one thing, you would have to go outside the community to find a mate. Other than that, I think it would develop along nomadic lines, with a chief of each seasteading tribe speaking for the whole seastead, and at the same time, being the head of the family.
If I had to live on a single small seastead in the middle of the ocean with my entire extended family of four generations, the only problem I would run into would be running out of bullets with which to shoot everyone.
I reckon I could live with my cousins without killing them… I can tolerate my brother…
Who said it would be small? It’s going to have to be big enough to support several dozen people… it’s not going to be cramped, overwise what’s the point?
As for having to go out of the community to find a spouse, that’s only true if you can’t get over the feeling of squick that comes from marrying your (3rd) cousin, even though there’s no problems with inbreeding (if they’re closer than 3rd, though, you do get problems – purely out of interest, I looked into it). Though, there’ll be plenty of opportunities to meet new people, I’d imagine, especially if you’re going to university (which raises a point about formal qualifications on a seastead…). Even if you don’t, I’m sure there’ll be seasteading get togethers with other clans…
With nomadic seastead tribes, that’s less of an issue, since there’s going to be plenty of trading going on between the seasteads.
I could see someone setting up a seastead as a university. As for training up the children… there’s always homeschooling. Each set of parents responsible for teaching their children until they reach college age. Then send them to university or teach them the family business. In fact, I kind of like the idea of guilds and apprenticeships. That is, after all, where universitys originated. That and monasteries.
