I'm not sure I agree. Replicators are basically just better 3D printers, and those are pretty readily available.

Username checks out.

They might be more interested if the TNG remastered sales were better. The pricing scheme on them was absurd and drove off potential customers, though. IIRC, waiting for the complete series set was actually more expensive than buying the seasons one by one as they came out.

Jack getting into Starfleet and assigned to a ship so fast can be easily explained with Starfleet being low on people after the events of the show. Also, he's still an ensign, so he didn't get jumped through the ranks. His bridge position is also something that Seven gave him as a special assignment rather than a standard bridge position specifically because of his background. He's essentially a formalized version of Mariner's role on the Ceritos.
