Can you really just change the place of incorporation? I thought to avoid a determination (under these laws) that Amazon itself has a physical presence in a state via its affiliates, Amazon was refusing to accept affiliates who had any physical presence in the states in question. As I read it, if your corporation is incorporated in Delaware but has its offices in Connecticut, you're no longer eligible for the affiliate program.

Enforcement might be another matter; seems like there's a good chance that you won't get flagged if you give Amazon a Delaware mailing address, even if you're (as a company or individual) resident elsewhere. But you don't even need to incorporate to do that.
