Am I missing someplace where my post dismisses the issues you’re talking about?
Not explicitly, no.
I would characterize the difference in our views (as I understand your views) as having primarily to do with expectations about the distribution of outcomes w.r.t. whether any given accommodation will be positive-sum, zero-sum, or negative-sum (and the details of how the benefits and harms will be distributed).
If one believes that the distribution is skewed heavily toward positive-sum outcomes, and zero-sum or negative-sum outcomes are rare or even essentially of negligible incidence, then the emphasis and focus of your post basically makes sense; in such a case, overlooking opportunities to provide accommodations is the primary way in which we end up with less value than we might have done.
If one believes that the distribution contains a substantial component of zero-sum or negative-sum outcomes (and, especially, if one believes that there are common categories of situations wherein a negative-sum outcome may be the default), then the emphasis and focus of your post is essentially mis-aimed, and the lack of discussion of costs, of harms, etc., is a substantial oversight in any treatment of the topic.
That said, I of course agree with the basic thesis which you express in the post’s title, and which you develop in the post, i.e. that not everything is a curb cut effect and that there are different dynamics that arise from different sorts of accommodations. You can think of my top-level comment in this thread as additive, so to speak—addressing a lacuna, rather than directly challenging any specific claim in your post. (My other top-level commentdoes directly challenge some of your claims, of course. But that’s a different subtopic.)
That makes sense, thanks. I should think more about cases where design for accessibility just generally makes something worse. You could shoehorn that into the handicapped parking paradigm but it’s not really the best fit—the challenge there isn’t allocating a limited resource, though there probably is an underlying limitation in terms of budget or attention. Those are frustrating because usually you can imagine a thoughtful solution that would make everyone happy, but you can’t count on it actually working out that way.
