I'm just saying that if a project is considered bad planning an art gallery isn't going to change that.
That would depend on whether the flaw lies in the project...or the planning it apparently fails to conform to.
Also, an art gallery could change that if what was "bad" about the project was it's lack of cultural benefit.
The increased residential population of downtown is going to keep on increasing...and increasing in huge numbers. It doesn't matter if the block-by-block density numbers vary. Worrying that hypothetically every square foot of downtown is going to have the same density as this is silly. That's why this "precedent setting" thing is such a false dilemma.
