California Consumer Privacy Act 2020

[_subgenius]

A sweeping new law that aims to rewrite the rules of the internet in California is set to go into effect on Jan. 1.

Most businesses with a website and customers in California — which is to say most large businesses in the nation — must follow the new rules, which are supposed to make online life more transparent and less creepy for users.

The only problem: Nobody’s sure how the new rules work.

The California Consumer Privacy Act started from a simple premise: People should be able to know if companies sell their personal information, see what information companies have already collected on them, and have the option of quitting the whole system.
...
Thanks to the technical complexity of the system and the rushed timeline for implementation, a number of basic questions remain unanswered. What does “sell” mean? How can companies be sure they’re deleting the right person’s data? And does simply having a website that keeps track of how many people visit each year mean you must wade into the regulatory thicket?

(emphasis mine)

So, is there value in this law for the people of California? or is this just another burdensome regulatory response to the free market justified by "just because"?
wouldn't it be easier to just forbid the collection of such data? and then devise a revenue generating method for the exceptions?
