If you share it with them, each time their freighters come, they will buy it from you (you will get money from it, but its negligible) and take it back to any of their Colonies with Starports.
Once the extremelly rare luxury (there are 3 extremelly rare ones wich give "strategic" benefits) reaches their Colony, their colony development will sky rocket upwards 50%!
The value of a Colony follows this formula: population x development= value. And a % of the value gets in their hands based on taxes.
If you DONT TRADE it with them, there will be more for you, for your own colonies. You cant send a fraction of it to all your colonies, because thats handled by the PRIVATE, so depending how far that luxury is from your StarPort Colonies (it seems only colonies with starport matter for this) you might not be able to make it "reach" your colonies.
You cant control wich colonies get benefitted directly.
I wish we had more control over it resources.
If my enemy needs chromium and he doesnt have sources, I should be able to prevent him from buying chromium from me. Not just those 3 extremelly rare luxuries. Same thing with all luxuries, each luxury increases development by 10%, so any close neighboors will end getting the same development level as you, because they will leech your luxuries sources by trading (and this is done automatically behind your back unless you set up a trade embargo, but this is too harsh of a measure, not enough fine tunning) and what benefits the player gets? "The raw price of the luxury", wich is negligible compared to the bulk ammount of GDP each luxury type will generate (10% more development).
Thats why I would like to prevent other factions from acessing all my luxuries. But these 3 extremelly rare luxuries, work the same way, except they increase development by 50% each! Godlike stuff.
Benefits of sharing? not having the slightly negative reputation and the raw price of the luxury (insignificant, even it says the price is 332,3, while everything else costs 0,5, because whatever colony gets it will generate MUCH MUCH more income than what you get, so you are helping them more than helping you)
Best not to share, only exceptions would be those you have strong alliance/dependency and you actually want to boost them to use them as tools in wars or something.
