You're saying a faction would hamstring itself by not using such a great technology. Cartographics getting real time updates on discovered systems. Man that is crazy. It doesn't make any sense what so ever.
Please use some logic.
And you are still desperately trying to defend it for no reason at all when there are far better ways to implement it. Why?
In a world that is steeped in corporate catering, where political and corporate interests overlap, you can bet that there are technologies that are patented and closely guarded secrets. While we are part of a very exclusive Federation of Pilots, that has a massive news network and probably connections far and wide in order to keep itself politically neutral. You could argue, that they do not allow other factions to use a certain technology.
Same is true for the federation of the Imperials. If they found such a great technology, they would only share it with their most trusted pilots and subjects.
Now if you think that is a 'crazy' argument, then you should try and read, what goes on right now, in our time. Patent loitering and patent obstructionism is a very real, and frustrating thing that basically hamstrings other corporations from using a specfic device or utility.
The entire Background of Elite is based on the fact that corporations became as powerful as nation states, so you bet your that there are regulations and rules in place to stop the sharing of technology. Especially from the Pilots Federation, an organisation known to be elusive and coy with their technology and political dealings. Because you can't see the logic in something, does not make it implausible, it just means that it doesn't make sense to you.
So as a counter to your "Please use some logic" which only serves to belittle and antaganize someone, "Please use some real-world logic"
I agree that the holo-me is a rather cheap work-around. It is a compromise that exists until space legs are actually implemented, because it the feature would only be hamstrung by it's dedication to a system that hasn't even been implemented yet.
This discussion and line of thinking is more important, when we actually get Space legs, but for now this entire discussion is a moot point.
