I wasn't asking about a system, I was asking about a PLANET!
Why would anyone use a walkie talkie to talk to someone next door when they could just go talk to them? No good reason to go out an buy one, I agree. But what if you already owned a walkie talkie to talk to a friend who lived a mile away, might you then be tempted to use it rather than walking downstairs?
Oh and the second reason I gave applied to comms on a planet.
A lot. But ther'es allready more than enough of them in orbit. And in 200 years or so when having space fighters and freighters, the cost of a satelite would be minimal.
And everything we know indicates that subspace tech ain't cheap.
We only know that jump drives aren't cheap. You might as well say that torches are expensive cause it costs a fortune to buy a military laser. We have absolutely no idea how much a subspace FTL comms device costs. Might even be cheaper once you factor in the not having to pay for satellites etc.
