> I mentioned in another post it's mostly row houses

This is incorrect. That does not describe the majority of housing units in NYC.

> The dumpster would go at the end of the block, no one will support walking that far with their garbage. Not when they are used to a different way.

I don't know why you're so confidently making this claim, because that's not what's being proposed or being done. There already is a pilot program for containerized trash collection, and - surprise - there's not just one container per block.
