Larian had enough money to finish the game. The kickstarter and Steam Early Access have allowed them to add more stuff and will let them take more time to polish the game before release.
There were retail and distribution deals in place before the kickstarter (and mentions of Steam and GOG included the phrase 'if available' at the start of the kickstarter). That is how the localizations were done, by making a deal with a distributor / publisher for a region. That is why Larian was able to announce specific release languages at the start of the kickstarter, and said other language could be available later if they were able to get a distribution deal.
Larian has already stated that the current Steam Early Access pricing is the release price, for both retail and digital.
Are you saying that Larian has to abandon retail releases in order to make games for gamers? How fair would that be? Not everyone lives in places with cheap, reliable and fast internet, and at least for now retail is a significant portion of the market.
It is retail pricing that necessitates regional pricing. You may not think different prices are fair, but the majority of people in a particular region do think it is fair, since they keep buying games at the listed price, and retailers and distributors / publishers remain in business. The EU is an exception to a straight supply and demand argument, since the economies there vary much more than any other currency based region.
