The writers (Pournelle, amongst others) that introduced the low tech idea were, of course, rationalising a setting for their stories. People here are extending this by taking it as the truth in their Traveller universes. (Which is fine, for any specific campaign.)Originally posted by Drakon:
That infrastructure needs to be brought with you when you set up the colony. Or else your cars are useless. You need to import the fuel, and spare parts with the cars, and all that increases the cost of your colony's transportation. If you have a device that depends on something being on the next transport, you got problems. The device is far less useful.
Unfortunately, in the general case, it's complete bunk.
In the real world, most imports are shipped by sea. This involves considerably longer periods of time in transit than are involved in travelling by J-Drive. It's not clear that transport costs are proportionately higher (or that much higher...) for interstellar travel at instellar TLs than they are for maritime travel at the present TL.
Most present day countries import oil, even if they produce it themselves. Most present day countries import vehicles, even if they produce them themselves. Most of these countries import spare parts for these vehicles as well. Many of the vehicles they produce use at least some imported parts, too...
No country on Earth is entirely self-sufficient. All countries are dependent on imports.
The arguments for low tech colonies are absurd. They essentially are based on the idea that imports are too expensive, or too sporadically available, to be worth using. This may be the case, but it hasn't been demonstrated. A more credible case could be made if colonisation was occurring on a sublight basis, with an extended timelag between vessels being sent and arriving. This might also be true if you were engaged in something like the Zhodani Core expeditions, where it can take decades to travel the full length of the route. But these are more likely to be a product of serial colonisation programs, where local infrastructure is built in one place, and then used to support the next colony. Each particular link in the chain wouldn't need to be especially long.
Let's be clear about this: part of the costs of, say, running a mine are the costs of bringing things like fuel and vehicles to the site, as well as building roads, installing and maintaining things like generators, and the general creation of all those bits of the infrastructure of civilisation that aren't available in the particular area that the mine is located in. Often, of course, all or most of that infrastructure is already available. Your mine might happen to _not_ be located on some island in the South Pacific, in Alaska, or off in some desert somewhere. It might be in New Jersey.
A colony is exactly the same. In fact, a mine in a remote location is _exactly_ a colony. For the duration of the mine's production, people will be living there. If we look at Earth, the settlements that build up around it may be non-existent, or may be quite substantial. And, of course, where there are people, there will be the possibility of other enterprises being founded. And, of course, once you have iron (for example) being mined, why not locate a steelworks next to it? That way, you increase the value of the goods you are shipping out. This is a logical enough next step. But maybe you need a source of coal force. Funnily enough, your exploration teams have been out there ever since your colony was founded...
A Wild West farmer mentality isn't really quite adequate for understanding colonisation. It can be the truth sometimes, but it isn't the whole story. It's not even the only alternative for agricultural and pastorally oriented colonisation programs. Plantations and ranches can actually often work better if they are large scale, high tech enterprises, rather than the property of individual rednecks. Of course, the latter _may_ have to depend on low tech, and _may_ have actually migrated in order to win their freedom to marry as many of their cousins as they like, but, frankly, who cares?
