We do affect things. We affect a lotI am personally of the opinion that the logic of the time loop is fine, but Venat's actions post-Elpis are either under-explained or too reliant on doing things because we told her it would happen. She should have her own reasons for acting in accordance with what we described.

My opinion is that we were in an altered timeline from the beginning of ARR.
Basically, Original WoL goes back to Elpis, finds out about Meteion and then returns to the Original Timeline, leaving Venat to play out her role in the story as originaly described to her.
The Original timeline doesn't have a tagged Meteion, but the new altered time that we've been in since ARR is the one with the tagged bird. Original time goes through the Exodus on the Moon and finds another way to Meteion.
Meanwhile, we get the events of Endwalker. Its the only way the Elpis part of the story gels with the time travel rules they set out in G'raha's story.
