I don't think the FTTN strategy was necessarily a bad idea, but they needed to put nodes closer to homes.
Just how are they supposed to do that? The VRAD nodes are placed adjacent to the existing SAI fan out points of the F2 lines.

Placing more nodes would require chopping up and re-engineering the copper network to include "mini-SAI"s with each of these new nodes (mini-VRADs) that you want to deploy. Can you imagine the POTS outages this re-engineering program would cause while the new SAIs were installed?

If, say, they halved the copper loop distance with these closer nodes than what they have now, that would mean they would be installing at least four times more SAI/node boxes than they are now. Certainly these hypothetical boxes would be smaller than the current VRADs because they would be designed for fewer connections, but four times more installations would cause more grief from four times more property owners that would find these new boxes installed on their property ROW.

The current overbuild VRADs are installed next to existing SAI cabinets which are often the same height or taller than the VRAD additions (a fact that Karl always fails to report in his "VRAD exposes" ). The property owners already know that they have a cabinet on their property so the addition of a VRAD shouldn't be such a shock to them.
Wrong.

Here are 2 examples of VRADS 100s of feet away from the neighborhood cross connect cabinets. Doesn't help loop length either.
