How will this affect colonies and effective power curve? will having to install alpha cores in everything still be necessary to get a leading edge on expedition and pirate raids?
I had a brand new colony go straight into heavy industry after the spaceport finished because I wanted to make ships I couldn't find in markets, and I had it for 60 days before the Persians sent an expedition to disrupt it for 160 days. Colonies take alot of income and money for initial buildings and upgrade and maintain, and putting high commands with alpha cores in them in every colony because expeditions, pirate raids, and ludic path cells tend to pile on as soon as you have anything of the slightest value, and you either go full on colonies with alpha cores, or you baby sit them. And if you don't have alpha cores and high commands on everything then the expeditions and pirates get through, then your colonies will be weakened and they will pile onto an already weakened colonies starting a death spiral.
Yes you can hire administrators and put points into administrator colony skills, but good administrators are usually only found during exploration and that requires not having to babysit your colonies, and not putting points into fleet and combat skills will get you killed when you eventually get sandwiched by a death fleet like 6 pirate armadas in hyperspace.
You're probably right. But bribing the expeditions gets more and more expensive each time, and having to plan to bribe the major 'civilized' factions to leave your brand new colony alone that still size 3 and only has two buildings seems like something you shouldn't need to plan for, and letting them disrupt it was the cheaper option. There's no option to not export stuff and not appear on the global market to avoid attracting their attention though, or alternatively only sell to the black market.
