This sounds like the perfect plan to further isolate and ghettoize inner cities...
You can count on lefties doing, whatever the problem, a "solution" that will make it worse.
To be a leftist is to forever have the cart before the horse.
Leftists wanted to "get people out of their cars" and into mass transit, so they reduce available parking downtown.
They want to stamp out petroleum, so they close pipelines in favor of Warren Buffett's BASF rail tankers.
They want to grab all privately owned firearms, so they restrict the manufacture and sales of ammunition because they can't ban the guns outright (yet).
The list goes on and on. They want to change a behavior they have no right to control, so they make it difficult to procure what's needed to exercise that "undesired" behavior.
