I don't think that it's meaningfully possible to opt out or delete, so this is a purely academic question.

You can factually opt out AND delete the data if you’re a California resident - as specified by the above link.

Not to a great enough degree, though. Just try opting out of the major data collectors, such as LN or credit rating agencies, and see how that goes.

Also, it does nothing for people who aren't in California.

California's law is much better than nothing, but it's not as good as the GDPR and the GDPR isn't really adequate.
