Keeping in mind I typically spend 2 story points on the spaceport for +20% access, if you have a Dealmaker Holosuite, I'd say it is definitely worth it, and probably throw the 4 story points on the Commerce as well, for a +100% credit buff without Alpha Core. I'll note in the attached pictures, all worlds have a High Command, except the 1st one (New Sahara). New Amazon has an no story point Commerce building and 2 industries, while New Arctic has 3 Industries. This is with freeport on, at a distance of 18 light years to Askonia, and I made a deal with the Pathers.
If I had another dealmaker and spent 4 more story points, New Amazon would be at around 180k profit (thats 2 industries and a the upgraded Commerce). Note, if I was using human administrators and the character as admins, stability on New Sahara would be 8, but all the others would be 10. Since largest, most stable world is used, for pirate activity it counts as 10, and is easily handled by the -18 bonus. Dealmaker + Mine is only Pather interest of 5.
So even without cores and only a dealmaker, a size 6 world is likely bringing in 250,000-300,000 at stability 8 (again, 6 story points spent, 2 on port, and 4 on commerce, removed the 5th industry). A 2 industry + Military + Commerce would bring in 150,000-180,000 at stability 10.
