account deactivated - just in US, Canada, Mexico - Account health affected

My account has been deactivated. It turns out that this applies only to the US, Canada and Mexico markets. Amazon probably needs some tax information. In the email informing me about deactivation, I was asked for virtual identity verification. What if I don't want to have access to the US, Canada and Mexico markets? I did not ask for access to these markets. Why did the problem appear now? Can I do nothing about it, or can we turn it off permanently?
