technical response
Wow... I didn't realise this was the holier than thou forum of self righteousness. Better find another forum where they can respond on the technical questions rather than the morality of asking.
To the original question... I had this same problem with sales tax, having moved abroad to Europe, but still having to pay sales tax for software purchases in the US.
I suppose I could move to using the app store netherlands or uk or norway (whereever my job takes me that year), but I hate managing multiple itunes accounts and logging into each with a different account every time there is an app update.
I could also use my old state where I used to live (NY) and donate tax dollars there even though I don't live there or have any ties there. Or maybe select some other state that is "in need" of tax dollars according to some in this forum.
But... no. Not going to do that.
My solution, which seems to work thus far, is to use a Delaware address with a prepaid credit card, e.g. American Express or Visa, purchased from any CVS store.
The government(s) will have to settle for taxing my house, car, fuel, wages, company profits, company expenditures, capital gains, interest, retail purchases, and air travel.
