It’s fascinating (and honestly a little tragic) that a lot of the cookie chaos comes down to basic unsolved problems like "how do you remember privacy without remembering identity?" — fundamental contradictions nobody could easily patch.
It really hits home what you said about the EU approach: case-by-case "squishy" regulation vs hard-coded universal rules.
Makes me wonder if any browser-led technical solution would just end up becoming de facto case law too — basically "Chrome/Firefox/Brave do it this way, so it becomes the norm," even if regulators never mandate it formally.
If you had a magic wand: would you push for a formal browser-level privacy protocol now, or is the better play just to keep tightening enforcement against the worst actors and let good practices spread organically?
