Looking at the linked thread, and assuming the info reposted here was from the original author "Editor" from the other board, it looks like a personal crusade thing to me. TEB is crowded, sure, but a solution has to be a *reasonable and well-planned* one. Closing the airport? That's a knee-jerk reaction.
Take a look at how the Meigs field closure in Chicago has affected ATC operations in the Chicago area. Meigs wasn't as busy as TEB in terms of bizjet traffic, either. I would imagine the impact on NYC's airspace with a closure of a field of TEB's magnitude wouldn't be pretty.

The first article on that page mentions how increasing traffic at O'hare and Midway (partially due to the Meigs field closure) is bogging down ATC at those fields. Given how everyone screams about delays delays delays and incompetant service from airlines and atc, one would think that "the public" would want to relieve congestion at the busier internat'l airports. Delays at EWR could only increase (likely dramatically) were TEB to be closed, and all that bizjet traffic re-routed.
The second article on the page talks about how the closing of Meigs field has impacted atc at OHare and Midway, citing an increased number of errors at those airports. So.. not only do delays go up, efficiency and safety go down...
But hey, so long as it's not in *MY* backyard.
