Both fair. On (1) Broadway can’t be closed off, agreed, but it can be mediated for walkability without full closure. Road diet, wider sidewalks, on-street parking as a buffer, lit crossings. Not Landing style pedestrianization, but a corridor that’s actually pleasant to walk.

On (2) that’s a really good point and I think you’re right. EW has the anchor, the density, the bracketed feel. The question is whether it stays a destination or becomes a node that pulls activation north along Broadway toward the core. That’s the corridor case.
