Why should somebody pay latinum for self sealing stembolts when they can just go to a replicator and make them?
I came up with this JirinPanthosa
Let's say you want one kilogram of antimatter. And you have a replicator connected to a matter/antimatter reactor. How many kilograms of antimatter are you going to "burn" in the m/am reactor to produce one kilogram of antimatter in the replicator. One for one? More?
If your using up five or ten kilos of antimatter, to make one kilo in the replicator, then producing the antimatter some other way makes more sense.
It's the same way with the stem bolts. Trading the land for the stem bolts is 'cheaper" than paying the price of replicating them.
We see people in Star Trek still engaged in mining. So if you need a million tonnes of some metal, it's more desirable to obtain those metals through extracting it from rock, transporting it across interstellar distances, and forming them into a shape --- than having the metal replicated. It's more economical.
