The decadence of the public services happened within the existing, non-libertarian legal framework that provisioned the publicly-funded police, the monopoly of land, and the public ownership of roads. The input into this model was the starvation of the government by means of cutting its funding, the output was its decline without a viable replacement. No libertarian theory that I've read proposes that social elegance emerges out of the mixture of the new and the ancien régime. Local policing and national defense are often theorized as funded by property contracts, rents, and fees on consumption and on fuel. The distinction from the usual taxation is that the individual retains the freedom to change property and location, and opt out.

It was movement in a libertarian direction, and failed.

True enough, you don't usually get "full blown libertarianism", because, well, hardly anyone wants that, which means people don't vote for it. Would make for an interesting experiment, though.
