Privacy Laws from what I've discovered are somewhat the same in different countries. For an example; Here in the US California Consumer Protection Act $($CCPA$)2018,$ The CPRA imposes even more stringent privacy protection obligations on organizations and greatly increases the rights of consumers, whereas the Australia Privacy Act regulates the privacy component of the consumer credit reporting system, tax file numbers, and health and medical research. APP entities are required to manage personal information openly and transparently and take such steps as are reasonable in the circumstances to implement practices and procedures. While privacy laws establishes ten legal bases for lawful processing and handling of data, as well as accountability requirement.

To me the privacy laws between the countries aren't any different, and if they were they have a very slight difference. The basic differences are that the US state laws are more target in their scope and contain a narrower set obligations. The biggest challenges for holding a particular nation or company accountable would be for the costly and time$-$consuming legal disputes. With that I don't disagree nor do I agree.
