Same reason people breaking into a website using a bug should be punished. The bug shouldn’t be there, and if you find the bug and do a responsible disclosure that should be fine, but to ezploit the bug for your own gain is not ok.
Do you live your life by the idea that anything not specifically illegal is acceptable for you to do?
Probably not because a lot of societal norms are regulated by shame and shared ideas of decency. This decision was made by a person or small group of people inside Amazon. Maybe those people wouldn’t have made that decision if their identities could become public?

This seems like deliberate silliness. Someone somewhere is writing down rules about how much money they get from you. If you don't obey the rules you get locked up. If you do obey the rules you don't. This isn't about doing things not specifically illegal; this is about how it's okay to obey the rules someone wrote down.
Where do you draw the line? When religion gets a foothold in a place then popular sentiment, imparted by religion, can be made law. Examples: Homosexuality, women showing their faces, women travelling without a male family escort, all illegal.
There is a saying: "Legislate in haste, perish at leisure". Not all things should require legislation, and those that are to be legislated should be fully and thoroughly considered. Often times it can be best to rely upon the moral will of society to impart a desired action than it is to strictly enforce compliance with that action. Its not perfect, but neither hard-line or soft-line is.
I hate to godwin this, but you realize that a lot of atrocities that have happened throughout history have been legal, right? Japanese internment was legal. South African apartheid was legal. The trail of tears was legal. American slavery was legal. The holocaust was legal under Nazi law. Legal != perfectly acceptable.
