Yes and no.
Money, like life, will find a way. Part of the issue here is the "Big- Ship/Small-Ship Universe" paradigm split. Specifically, What's a typical amant of traffic?
I agree, and my comments have supported, that money will find a way...
But, you have to have Money first.
And, even when you do have the money, there is a break point at which the cost will be too much for an item no matter how much money you have.
Added to that, the point I am arguing against is
@mike wightman 's assertion:
"The Imperium promotes free trade, if you want a TL15 item but you live on a TL9 world just order it and pay the shipping cost."
Where Money may well find a way, this assertion is anyone can simply pick up a comms, spark up the vid, wrap a message around an arrow and order anything
But, "Money" is not the average person.
Proponents of
@mike wightman's point of view quickly supported narrowing down the discussion to "Rich people can"....but I have repeatedly pointed out "everyone" is not rich.
Some examples of this are Pavabid(District 268/Spinward Marches). There, all of the highest rank of leadership live in a floating city above the fields their populace work. Literally no one else can order jack from off world. The leadership tell them that is heresy. And yes, I do admit this system is outside the 3I, but still. They do "have the tech" there...So, this qualifies under
@mike wightman's assertions.
Let's look at my previous example, Pimane(Mora/Spinward Marches)
Two parsecs from a TL-D world on one Xboat route and 2 from a TL-9 world on another. Not to mention, 6 Parsecs from Mora itself.
But they have no atmo, no hydrographics, almost no population and literally nothing to sell
IMTU, they were a mining world when Imperial settlement of the Marches was new and Jump 4 was what Jump 6 is now.
IMTU, they are what is referred to as a "Ghost world", where the mines played out and those who could left.
The rest are essentially trapped by economics while the Xboat route and trading ships pass them by
They'd be entirely cut off if they were not on a "Must call there Once every two months" charter assigned to a Subsidized Trader.
But, again, they have nothing to trade. So, even the masters of Subsidized Traders might try to find a "legitimate reason" for skipping them
Look at the Spinward Marches and you see many systems "out on the strand" where almost no one "wants to go to"
All those systems are certainly not what you, or anyone else, would call "Money"
And, all of those are societies which can't simply pick op the comms and call Amazon...or Sears...or whatever.
