The argument against being able to seek passengers and freight to multi-jump destinations is that with the RAW there would be just as many passengers/freight lots for the slower, more expensive multi-jump trip as for the quicker, cheaper single-jump.
That is the glaringly obvious problem with multi-passages. Why pay more AND take longer to get there.
True ... but also slightly misleading.
Let me explain what I mean by that.
With all else being EQUAL ... the assertions made that "no one" is going to want to pay more to reach the same destination IS TRUE.
What is NOT true is the "all else being equal" part of the equation under all circumstances.
To highlight the point I'm wanting to make here, let's think in terms of two opposite ends of the commercial continuum circumstances.
- High population (8+) world on a "big" trade route with LOTS of interstellar traffic flowing through.
- Low population (4-) world that is "away from" any highly profitable trade routes which hardly any merchant starships go to.
First question:
Are the opportunities for interstellar transport services going to be "equal" in these two contexts?
Answer:
DUH. NO. 
When the difference is between "hundreds of starships arriving and departing daily" on one end and the alternative of "maybe a starship shows up once per season of the year" ... the whole
all else being equal part of the equation vanishes, because the circumstances are NOT EQUAL.
Then there's the "lock in" factor of first come/first served for the external 3rd parties.
Let's say that there are two starships heading for the exact same destination.
One of the starships will be going there in a single jump, while the second starship will require multiple jumps (2+ for the sake of illustration purposes).
With all else being EQUAL ... the single jump starship "gets all the tickets" because that costs less to the buyers, while the multi-jump starship "gets NONE of the tickets" because the service they're offering costs more (minimum 2x more).
But then what happens if the single jump starship doesn't have the CAPACITY to sell tickets to everyone who wants to buy them? The single starship fills their manifest and then has to turn away buyers for more tickets. The whole "no room left at the inn" factor comes into play.
So everyone who COULDN'T get a ticket on the single jump starship has to go looking for backup options ... at which point the multi-jump starship (requiring multiple tickets) comes into the picture. The multi-jump starship becomes "available" (at a higher price) for all the tickets that want to go to the same destination as the single jump starship. This becomes "viable" simply because transport options are limited ... and demand for services outstrips the supply at any given time.
Classic laws of supply & demand.
When demand for a product or service is higher than the supply ... the price for that product or service goes up.
Therefore ... when all the single jump to destination tickets get sold out, if there is still a demand for tickets to get to that same destination, there will be buyers for multi-jump tickets to reach that destination ... even though the transport cost to do so will be higher. Maybe not AS MANY buyers as the single jump option, but the demand will be "above zero" in all likelihood.
Why?
Because the demand for interstellar transport services is higher than the capacity of starships able to supply those services.
And yes, the multi-jump option may "take longer" to reach the destination, but the multi-jump option WILL GET THERE within a predictable amount of time (barring misjumps, of course). Waiting for ANOTHER single jump starship to show up and sell tickets to that destination
on a shorter time scale than the multi-jump option then becomes a classic gamble on the outcome of future events. In other words, "a bird in the hand is safer than two in the bush" (or words to that effect).
The LBB2 ticket generation rules aren't "simulating entire world economies for import/export" (or words to that effect). Instead the LBB2 ticket generation rules are ONLY concerned with the fractional slice segment of tickets demand for a single starship owner. It's more of a "what's in stock right now?" kind of system for starship operators to interface with, rather than something which is trying to model the ENTIRE STARPORT ECONOMY and then determine which sliver of a thin slice applies to each starship.
