The collapse model says that after performing a local measurement, the wavefunction locally evolves from the eigenstate that has been measured, nothing else. For a local observer spacelike separated events do no exist until they come into causal contact with it. That's the earliest time that can be called a measurement time.

That sounds like mind projection fallacy. That the observer does not know about the events doesn't mean they don't exist.
That's the earliest time that can be called a measurement time.
That would imply that whatever measurements we make locally, from the perspective of an observer who hasn't yet interacted with those measurements, our wave function hasn't collapsed yet, and we remain in superposition.
So, how does it make sense that the wave function has collapsed from our perspective?

Discuss the post here (rather than in the comments to the original post).
This post is part of the Rerunning the Sequences series, where we'll be going through Eliezer Yudkowsky's old posts in order so that people who are interested can (re-)read and discuss them. The previous post was The Dilemma: Science or Bayes?, and you can use the sequence_reruns tag or rss feed to follow the rest of the series.
Sequence reruns are a community-driven effort. You can participate by re-reading the sequence post, discussing it here, posting the next day's sequence reruns post, or summarizing forthcoming articles on the wiki. Go here for more details, or to have meta discussions about the Rerunning the Sequences series.
