Parking structures are nobody's favorite project, but I am willing to believe that with the boom in occupancy, renovation, and new construction Downtown, there may be a market for more parking spaces:

What I don't believe is the claim by the Stabiles of the world that these parking structures need massive public subsidies. The sorts of people who can afford the rents that they are charging for new units Downtown can typically also afford to pay a substantial parking lease. And if in fact at the cost of financing a parking space they would prefer not to pay, then fine.
In that sense, parking spaces for Downtown residents are sort of like a second bedroom. Some potential Downtown residents may well want or need a second bedroom, and will be willing to pay extra rent to get one. Others will not need a second bedroom and would prefer to pay less. Developers can figure out the mix that makes the most sense, and charge rents accordingly.
But no one is arguing the public should be subsidizing second bedrooms just because some potential Downtown residents will want them. And we shouldn't be subsidizing parking spaces either.
By the way, all this was coming out of some mentions in the PDP's latest report on the State of Downtown, and it will come as no surprise it is full of very positive trends:

I think we should recognize that Downtown's momentum is extremely powerful right now, and for fundamental reasons. Accordingly, we should be very wary about big public projects (or publicly-subsdized projects), particularly ones that will dictate land use for decades to come. That is not to say there is no role for the public to play, particularly when it comes to things like public infrastructure and services, public spaces, historic preservation, and so on. But the time is well past when the public needs to play at being a main developer Downtown.
