1) The easter eggs are not impossible to find.
2) Having them be influenced by RNG does not stop us from telling interesting and consistent stories about them.
3) There's still plenty of interesting fixed landmarks for challenging other players.
4) If random generation makes lore impossible, please explain Dwarf Fortress. In Dwarf Fortress the world, the civilisations, the people, the monsters, hell, even the musical instruments are generated differently each time. And yet the community seems to have no trouble generating and expanding upon consistent interesting lore. How is this possible?
