(Admittedly, this is an oversimplification, construction costs do change depending on height, built form, economies of scale (repetition in floorplates), etc, but generally, the amount of saleable area is the key metric.)
So, the issue with the height limit is not really about project viability. Developers have shown they can make projects work despite the height limit. The question is: do the implications that the height limit has on the built form of new development make for better buildings? I have always argued no.
Take the above hypothetical. Instead of a thin point tower (750 m2) that rises 40 storeys, like one would see in Toronto or Vancouver, developers have to build towers with floorplates of 1000 m2 or more. From the public perspective, this causes: larger shadows that have less "movement", generally worse appearing width-to-height proportions, and increased blocking of sky views. From a livability perspective, this causes: worse floorplans that are more "bowling alley" style than a 750 m2 tower, more bedrooms that don't actually have a window, and so on.
Can these effects be considered positive? Can they be considered better than the alternative 10 extra storeys with a slimmer floorplate? I really don't see how you can argue that.
It doesn't stop at larger floorplates, either. We also see towers being built closer together, and sited directly facing each other. A 25 metre tower separation is generally the standard in Toronto, but in Hamilton, we continually see towers that are significantly closer to each other than that. Ideally, as well, we would position towers kitty corner to each other so you're not directly facing out towards another one. But this is much more difficult to achieve when you are forced to build larger floorplates and you have to build to less than ideal tower separation distances. From a public perspective, this again causes: larger shadows that "blend" together into one mass effectively negating that benefit of limiting tower floorplate size, and reduced sky views between towers, again, making it appear more like one massive structure. From a livability perspective: the amount of daylight that can enter a unit is reduced, and your privacy is reduced as you're closer to the condo tower next door.
Again, are these positive effects? Are they better than the alternative?
They are not serving the general public interest. They are not serving the interest of the individuals who will inhabit these buildings.
That, to me, makes the height limit indefensible policy. It is not spreading development around as some have argued, it is simply shaping the development that will occur in our downtown for the worse. The other practical argument that I've seen given in defense of the height limit, that it eliminated land speculation and will make development more affordable, is really disingenuous, because the so-called land speculation was replaced by significantly raising the land value in one fell swoop. (and let's be clear, there is still speculation ongoing — properties within the DTSP boundaries that don't allow the maximum 30 storeys spark questions of "what's the chance we can get that land increased to the 30 storeys that's permitted on the other side of the street?")
And, on a final note, by all means, increase permissions everywhere, and get rid of parking minimums — I am 110% on board, and believe those are necessary, overdue, valuable changes. Advocating that we should be okay with keeping a bad policy because there are other bad policies or because other areas are not pulling their weight is letting the perfect be the enemy of the good. We can, and need to, do better — and do all of the above.
