>The whole idea that you can be agile while having delivery dates for things several months in advance is a nonsense

If Agile truly rejects even the possibility of an estimation (something I'm sure many proponents will disagree with), that would be a problem with Agile and not a problem with the idea of estimation. Companies will de facto pivot away to methods that will give an estimation, even if they're 'bad Agile' and even if software engineers are unhappy about it.

Because there are more useful things to optimize for than efficiency of software delivery or what software engineers like. People really need to know when the works on their street will be done, companies and countries need to plan ahead, and so on.
