As long as they support open peering they can probably operate at

Perhaps, but well worth the effort. There are a wide variety of reasons
to want more than one L3 provider to be readily available and avoid
limiting consumers to a single choice of ISP policies, capabilities, etc.

If the municipal provider offers open, settlement-free peering at the
head end then the customer *does* have a choice of L3 provider. Tunnel
service over IP has only minor differences from an L2 service in such
a scenario. Only one difference truthfully: MTU.


No, they have the municipal provider as a single monopoly L3 provider.

While it's true that you can create an L2 service on top of existing
L3 service using a tunnel, that doesn't exempt you from the limitations
and policies of the underlying L3 provider.


Also, an L1/L2 fiber plant may be usable for other services beyond just
packets.

True enough but rapidly dropping in importance. The 20th century held
POTS service with a rare need for a dry copper pair. The 21st holds IP
packets with a rare need for dark fiber.


We all know these trends run in cycles. Today, the importance of other
services is dropping. However, if we should have learned anything from
the past development in this industry, it's that planning a 30 year plant
around today's realities is virtually guaranteed to be wrong in about 10
years or less.

Besides, I don't propose that a municipality implement fiber but
refuse to unbundle it at any reasonable price. That would be Really
Bad.


However, if they're competing for L3 business, it creates a conflict
of interest. If they're a monopoly L3 provider, it creates different
problems.
