Let's not get too rose-tinted with our spectacles here. Yes, internal consistency of the game universe is important, but the original Elite had plenty of places where lore was secondary to gameplay.
For example...
In the original Elite, holographic "telepresence" communication between systems exists (Rafe and Alex have a conversation this way during the Dark Wheel) [1,2]. There are other in-game mechanisms, such as bounties being transmitted between systems, your bank balance and rank being carried along safely, etc. that also rely on inter-system communications being at least as fast as the player ship is, and possibly faster. (How long a hyperspace jump actually takes is never stated, of course, until FE2)
It is also stated in the manual that "GalCop regulations prohibit planets from advertising their requirements or announcing their market prices beyond their own System Space" - and indeed, in-game, there was no way to find out prices without going there ... a constraint only recently dropped in Elite Dangerous!
But obviously, given the communications systems in place - and also the ability to ask a trader who'd just come from there! - it should have been possible to get at least semi-reliable information on prices, at the very least through illegal channels (may as well be hanged for piracy as for release of trade prices).
That wasn't what happened - the game just ignored that prices "should" be possible to obtain, partly because the hardware limitations of the time would have made it a little tricky to sensibly generate the prices before entering the system, and partly because it would have made trading far too straightforward and too easy to figure out the (relatively simple) rules. So lore was secondary to gameplay there. Rightly so, of course.
[1] There are also plenty of remote-controlled drone ships, like the one which rescues Alex in chapter 2, or the orbital shuttle in the manual, or the rumours that the navy is working on a Galcop equivalent to the Thargon. Oh no!
[2] Telepresence control of combat ships does not appear to exist, but you have to handwave an infosec objection to armed remote controlled ships being too vulnerable to hijack, as all the technology is clearly there to do it if people want to. (You could handwave the same infosec objection for Elite Dangerous, if you wanted to explain why telepresence is allowed for secondary but not primary crew.)
