You can buy ebooks from a Kindle Store from outside the U.S.. Let’s see whether it makes sense to have a U.S. address and whether you can buy ebook in the US Kindle Store using a U.S. address, while being outside U.S.A.

If you move to another country, you can buy about 5 ebooks using your U.S. address. But then you will get the following message:
Name Surname, please contact us or change your country to complete your purchase.
You attempted to purchase an item while in a different country than listed on your Amazon account.

Please contact customer service in order to continue purchasing Kindle items.

You can easily update your country for your Amazon account.
If you want to order ebooks from a US Kindle Store while using a U.S. address, being outside the U.S., and without contacting Amazon customer service, you need to use a U.S. IP address. You can get it by using a U.S. proxy server, a U.S. VPN (Virtual Private Network). You can also use Tor, but the latter is risky. When you have a U.S. IP address, you don’t get any messages and can buy ebooks from Kindle Store without any problem.
