The answer can still be NIMBYism, because a politician using eminent domain is political suicide with NIMBY’s around. Also, eminent domain is generally too expensive to pull off in a major city like NYC, because you to pay “just compensation” to those evicted (which is generally fair market value).

The answer is also that it’s too expensive, involves too much red tape (in both the executive gov’t and the courts), and therefore takes too long to sustain the political will needed to make it happen.
