It is already a monopoly. Most places are served by one of the utilities: power, telephony or cable. He that controls the outside plant controls your fate.
The difference is in how the services can be unbundled.
Power is additive (if in phase) that network topology is irrelevant.
For telephony, unbundling for DSL at L1 is just fine.
So is optical fiber if single star topology is used.
WDM PON can still be unbundled at L1.
However, with time slotted PON, unbundling must be at L2, which is as expensive as L3, which means there effectively is no unbundling.
Or, CLEC may rent a raw fiber at L1 and operate its own PON. However, as CLEC has less customer density to share the fiber than ILEC, CLEC's fiber cost per customer is higher than that of ILEC, which is why PON promotes local monopoly.
It doesn't promote local monopoly if you don't allow the L1 company to provide L2+ services. If the L1 company is required to be independent of and treat all L2+ services companies equally, then, the ILEC, CLEC, et. all have the same cost per customer. Owen
