gdpr doesn't stop governments. governments are already spying without permission and they exploit stolen data all the time. so yes, the cost of gdpr compliances including popups is higher than the imperceptible cost of tracked advertising.
For one that is objectively incorrect. GDPR prevents a whole host of data collection outright, shifts the burden for corporations to collecting the minimal amount of data possible, and gives you the right to explicitly consent into what data can be collected.
Being angry at a popup that merely makes transparent, what a company tries to collect from you, and giving you the explicit option to say no to that, is just infantile. It basically amounts to saying that you don't want to think about how companies are exploiting your data, and that you're a sort of internet browsing zombie. That is certainly a lot of things, but it isn't rational.
