So you say there is a problem with taxes, then you want me to come up with something better? There is no problem with taxes - tax is the correct way to pay for the incarceration of people who need to be incarcerated. If you have an issue with that, then you come up with something better. If you can't, stop bleating that society is "plundering" its citizens when it raises taxes to pay for the services they voted for.
I have no problem if the citizens in "your" society voted for a tax. Go right ahead and "plunder" each other. I did not vote for that so, therefore and thusly, I'm not in accord with your methods and means. Do not come after me to collect, for I did not give you my explicit consent to do so.
I will not use your services, so I should not be expected to pay for them. Thanks.
The incarceration of violent mentally ill protects you just as much as it protects any citizen.
The important thing here is that you agree the service is needed. You just don't want to pay for the protection you receive. Unless you have something more intelligent that "I want it for free and I want it now" I think your attempt to offer an idea for organising a society has just fallen apart.
