This can be said of lots of other issues like Safari's war on internet infrastructure by banning 3rd party cookies for no reason. Cookies are a known entity, easy to check and easy to clear, not to mention they also held opt-out status for all those networks that offered it. Progress should be understanding and choice, not brute force approaches like these that just fatigue users and undermine the entire cause.
Users who don't like Safari's privacy defaults can just change them, though. If you like understanding and choice, why not let users understand and choose turning third party cookies on, instead of turning them off?
The defaults are the issue, by going against the greater convention on something that only a few minority really have a big concern with. None of the other browsers do this and it hasn't really led to any privacy benefits, rather it's increased the level of tracking from something that was easily controlled and understood to now fingerprinting and even ISP level identification.
Cookies are internet infrastructure. Identity/state management is just a natural part of the way the internet works. This sort of thing would be better solved through regulation on the network side rather than just browsers doing whatever they want.
