Roads, schools and fire departments all predate taxes. Centralization brought them into the tax realm and they are all heavily controlled. Decentralizing them incrementally is not only more economically feasible, but it will allow for better technology to thrive.

ROADS

Take the road. Fuel taxes, registration taxes, inspection taxes and toll taxes are all collected for the roads. There exists concrete technology which uses bacteria to fill cracks and holes in concrete naturally. Self filling potholes? Imagine how much money can be saved in the tax cost of operating automobiles if they did not need to be constantly repaired.  Why isn't this tech used? Centralization.

FIRE COMPANIES

Take fire departments. Most are volunteer. They rely on donations and actually do pretty well. The state's infrastructure takes an average of ten mins for a fire department to receive a fire call through the 911 system. Instead, a Blockchain based fire alarm system can notify the department in seconds and when it comes to fire ten minutes can cause a lifetime of damage. Some parts of the USA offers fire insurance. For 20 dollars a year you get coverage. Now if your house has ems or fire call you aren't charged anything for service but if you don't have insurance you are billed for the costs associated. This has proven widely successful and used over a century. 

Same can be applied to auto insurance. New Hampshire has voluntary car insurance when Pennsylvania does not. The cost for full coverage auto insurance in pa avgs over $120 a month compared to $82 in NH. Competition drives costs down and holds people accountable for their actions. 

POLICE

Then there comes the question about police and their much needed service to the community. We could argue their actual purpose and if there is a need for a centralized police force, although let us answer how we could have police without taxes. The service of the police needs to be thought of like the service of EMS or Fire Company. When a crime is committed their services should be rendered just like the aforementioned services. It will cut down their costs and enhance the safety of the community. If your community wants to have them out and about roaming around that can be completely voluntary too. But an insurance program like the fire companies insurance programs would be better. If you don't pay and call police you should be charged for their time and resources. Show your police service insurance card and then have a very low deductible or have the service completely covered. This would lead communities to have accountable and efficient police services. Communities would also work harder to promote their friendly and low cost police services and the police would treat people more like customers and less like livestock.
