We're getting off-topic, but the idea that a group of people cannot get organized and live together if there no compulsory robbery system like taxes, is nothing else but millennia-long indoctrination.  Taxes are not needed to make the state function, the state is there to make the taxes function.

There's in fact a whole other "public finance" system that is possible: pay for those "public services" that you need and want (including police protection).  And another principle could hold.  Every economy is ultimately resource-limited, and the ultimate resource is natural resources and land.  These resources shouldn't be "property".  They shouldn't be allowed to be part of "ownership".   Nature and land belongs to all of us.  Of course, one needs land and natural resources to do production (and to live somewhere), but instead of granting property rights, one could just grant leasing rights in a public offering.  All land and natural resources are leased to the most-offering, and the payment of this rent replaces taxes.  You cannot be a land owner.  You can only lease land.  You cannot own natural resources.  You can only lease them.  And the rent you pay is what finances public spending.  Ideally, this spending shouldn't go to any government, but directly to the people, as a form of base income.  There is no clogging up of resources or land, and the real estate market would converge to its utility price and not become a collectible and monetary resource which it is now, because of course, real estate gets lost from its owner when the land on which it stands, goes back into the public bin for a next leasing cycle. 

So, compulsory taxes are not a necessity.
