I imagine part of the justification was, "If we don't use the TSI space now, it'll be much harder to access and use in the future when we build Villains. But if we don't use the BBTMRR space now, we can always use it in the future." The idea being 1) this is cheaper, 2) maximizes space, and 3) saves an expansion plot for later.
I agree that is short cited, but I imagine that was part of the argument.
This I actually agree with.
My problem is, there once was a Disney that used to care.
A Disney that wouldn't do certain things, if those things didn't fit the vision of the park.
I'll use the Guardians ride at Epcot for example.
By all rights, a great ride. (though I haven't ridden it yet)
But Disney of 'yore would have said "Cool concept... But you realize we can't construct a giant box clearly visible from many angles in Epcot?
Similarly, they would have said "You know... We can't cram the World Showcase Lagoon with giant barges and screens, no matter how great you think this show will look?
So, yes - there was a Disney of 'yore that would have said "Cool idea to add cars to WDW."
"But we're not going to pave over Rivers of America for it."
I also understand that there are issues with the river, and Disney would rather pave it over than deal with that.
Spend money on that.
Unfortunately this is no longer that Disney of the past.
This is a Disney that puts a static planter where a tremendous fountain was.
This is a Disney that removes an amazing landscaped fountain and rockwork structure in Polly, and sticks a statue there.
