Doc, the sentence before that referenced the IS and 'overall' as in existence. No matter what, their jumpship numbers are finite- IF they were trying to expand their mercantile sphere of influence either by gaining more colony customers or more frequent trips it would require more efficient use of those drop collars. My last statement was that they might not have gone in to the same degree the Inner Sphere should have, but still as they expanded trade they would want more cargo moved on those limited collars.
Weirdo, I agree with that but the smaller ship is only cheaper in it's operation- not the jump cost. The cost they pay to use the collar is the same for a small DS or a large DS- a large DS is just able to spread that cost out among more goods. I understand your example but consider this . . . during the age of sail- which oddly enough the end gets close to the same cargo load (ignoring BT's mass vs volume inaccuracy). During that time, cargo loads were things like precious metals, gems, alcohol, tea, spices, and fabrics- most high value, low mass/bulk with precious metals being a outlier due to the value. Cargo loads of things like bulk grain or other food stuffs were not shipped half-way around the world because it had no profit margin for the costs of transport. Fast foward to steam power and metal hulls which allowed more direct/faster transport along with larger hulls to carry more, and things that were previously unprofitable to ship became profitable.
So say when you delivered your Bop It IICs before you only accepted refined rare metals from mining worlds/colonies, and such things as rum, bolts of cotton or other fabric, concentrated organic dyes, and rubber extracts from ag worlds. Take a larger cargo ship and now you can trade for metals (molybdem vs say nickel) that would not have been profitable to haul before b/c the transport costs were too high- spread over a 1000 tons of cargo instead of 10+k tons of cargo. So now you might also import unwashed cotton (might be thinking of wool) which has uses for water resistant cloth IIRC, along with the bolts of cotton.
The colony can increase their production of raw materials without having to expand their refinement & processing facilities to make use of the increased production- broader base of the triangle without having to expand the layers on top of it. So, simplified example . . . every week the colony mined 10 tons of ore to refine and get 2 tons of pure ingots. Now they might be able to mine 15 tons, still refine to get 2 tons of ingots, but also because the dropship can haul away more they might be able to sell 5 tons of ore and 2 tons of slag that can be used to make fertilizer (to be sold to the ag world) back home.
It makes a feedback loop, the ability of a Hansa DS to take more in trade gives the world they visit more buying power, thus buying more Hansa goods.
Then again, this is all world building in a way FASA never looked at or really provided any guidance beyond 'the economy works.'
