For those who feel there's no return on investment, can it be considered albeit a stretch that the secondary return is less wear and tear on other forms of transport like boats, the ferry, buses, and monorail? It's a way for people to get around when factors interrupt transportation services. Maybe they could actually consider rehabing the monorail system after all.
Also not for nothing, but Disney ain't broke. I get that they don't want to spend more than they have to, who does? Especially when the exact structure built doesn't birth any opportunities for profit. But they're willing to spend on other projects that I'm sure could be argued are more frivolous than a walkway or bridge. Build this, raise the cost of XY&Z, more specialty ticketed events, raise ticket prices by a few bucks, hike the cost of bottles drinks by a dime. Not that this is ideal clearly, but they could do that. Isn't that how the recoup what they've spent on everything else they create or roll out?
