So in the setting of Eclipse Phase, the mind and the body are separate things, something that real life philosophers have been debating for a very long time and will likely continue to do so until the sun blows up. Cool, that means your mind can be digitized, edited, and faxed to other places in the solar system like software.
Which brings up the question: when you egocast, does the "you" that existed prior to the egocasting simply die, and another "you" wakes up somewhere else? Sure the memories would all be intact, and to the person on the other side it was a flawless transition. But for all intents and purposes the person that egocast before is effectively dead.
Now chalk this up to me thinking like a dirty bioconservative Luddite or having a "cognitional bias" (which, by the way, I think is an extremely presumptuous-sounding phrase and which I've heard a few times from people on forums discussing Eclipse Phase) but I don't consider that immortality. If I was told, as a player of this game, that "everytime you egocast you die but it's okay because you continue playing as a clone of you on the other side" I'm not sure I'd be okay with that. Assuming that when you do egocast your "original" self is killed, the only way to preserve your original "self" is if your cortical stack is retrieved, you are revived in a medical vat, or if you resleeve into another morph, which is impractical since to do that you'd need to be at least 10,000 km away to do so.
This is why I can understand and even sympathize a little with the perspective of biocons in the setting. Everyone who has ever egocast is dead. Now you just have people walking around pretending to be people who died. And what about if you died during the Fall and you're restored from backup? Or if you're infected by the exsurgent virus and you're restored from backup? How is that any different from an alpha fork if literally 99% of so-called transhumanity are just forks?
Honestly this is already a setting that already assumes that the mind is separable form the body, which we cannot yet prove in real life, so I go out on a limb and assume that yes, the original you that egocast from Venus is the exact same person to arrive onto Titan. How do they beam a human mind across space? A similar answer to "a wizard did it" in a fantasy setting I guess.
