Maybe taxes should be optional, taxpayers would get an ID, if you got mugged the police would need to see you were a taxpayer before you could file a report, the murders of non-taxpayers would not be investigated. Non-taxpayers would not be entitled to use the roads or the beaches or the parks. In an accident situation, EMTs would only treat taxpayers, non-taxpayers would simply be pushed to the side of the road. If a non-taxpayers house caught on fire, the fire department wouldn't put out the fire, it would just stand by to make sure it didn't spread to taxpayers homes.
Of course this means that non-taxpayers wouldn't be able to get a mortgage, because they couldn't get Fire insurance.
