This is a bizarre series of comments.
(Q1) Regulators should encourage competition? True/False
(Q2) All government services are monopolies? True/False.
(Q3) All municipal services are either (utilities, monopolies)? True/False.
These are all absurd formulations.
Public Services are a thing. Some examples:
Ex 1> My public library is an ISP.
Ex 2> My public library is Tax Filing Center.
Ex 3> My public library is a copyright depository.
Ex 4> My public libary is a copy/fax location.
Competitors:
Ex1'> Comcast
Ex2'> TurboTax
Ex3'> Netflix
Ex4'> Staples
I don't think the solution is to allow municipalities to do more things that undermine competition.
Again, this is absurd. Public services do not undermine competition by implication. This formulation is akin to saying: "a good competitor undermines competition by being good." Or, "a new competitor undermines the competition, by entering the competition."... Um, no.
This is not to say single payer healthcare would not change the business/policy landscape in the USA.
But to even suggest that any municipal provisioning of communications services (public radio, public TV, public internet access) would be aking to "single payer healthcare" in scale/scope/completeness etc is simpley a rhetorical exaggeration.
I think its interesting to debate the pitfalls here, butnot with such extreme poles as a starting point.
Limited scope incremental services are fine, IMHO. Feasible, cost-effective, and market & competition extending.
And the existence of national parks does not make the government a "land monopolist" or what not. =D
