Investigating murders is enforceable. If law enforcement isn't doing their job then that is a different problem. By virtue of being on the Internet, tracking cookies span many legal jurisdictions (even ones outside of the EU that never agreed to GDPR) and therefore run into all sorts of different legal obstacles. Apples and oranges and all that.
> This is just a libertarian fairy-tale that is designed to sound sensible and rational while being malicious in practice. It exploits information asymmetry, human ignorance, network effects, and our general inability to accurately assess long-term consequences, in order to funnel profits into the hands of the most unscrupulous businesses.
No, it allows people to be adults and vote with their feet. We do this all the time in many other areas and it works. (Exactly what the free market is based on) This is not to say that there shouldn't be any privacy and anti-spam laws, but when it comes to allowing marketing/advertising the trade-off has been well understood for some time. We are all funneling a lot of profits into companies that provide software to serve up the cookie banner warnings now and the advertisers still end up getting lots of people's data. A poorly designed law is a bad law. Legally requiring consent upfront and the ramifications of that decision should have been thought through much more thoroughly.
