The two other services rah should give pause are education and fire fighting. In many cases insurance companies pay for fire services only for their buyers. One could see this going towards crowd funding. Private school is also crowd funded. The teachers unions seem ok with this since it doesn't pull resources away. (The private garbage model). They do raise hell for charter schools though.
The same encouraged privatization and evaporating public support has been happening for years, especially in my city (Philadelphia).
Last week a young girl died because the city's budget only allows for a nurse at her school two days a week. No one on duty had enough medical knowledge to recognize her asthma attack required professional attention.[1]
A supplement to the devestating education budget (this year began with roughly half the number of operating schools as the last) comes from city-encouraged philanthropic donations.[2] There are already nation-wide crowdfunding efforts, such as Donors Choose.[3] Some schools in Philly need to go this route to get supplies like paper and pencils.[4]
There is a lot of documented experience on how private fire services work and where they fail - for example, New York experience with private firefighting companies is not that old and very interesting.
