Does this vow implicitly declare that you do not recognize society's right to tax it's members for the communal obligation to support the roads, the health care system, social security, etc?

On the contrary. Conventional money doesn't serve well the process of community contribution and solidarity, because of the perverse effects built into its core(condensation, centralization, scarcity, opacity, proprietarization, etc). If we really want to honor our communal obligation, it should be done with appropriate currencies.

Some countries, and a growing number of cities and regions, are opening the path towards more appropriate currencies:

• in Japan, the Furei-Kippu is a time currency that helps organize neighborhood solidarity, specially for the elders ;

• in the USA the government accepted time-banking as a non-taxable solidarity currency ;

• Europe is financing the SOL social currency ;

• in Germany many regions are developing the Regio, a currency system for sustainable local economies...

The list goes on and on. Many alternative currencies are flourishing around the world, they are motivated by the dysfunction of conventional money.

The MetaCurrency protocol and the rise of flowplaces are going to accelerate the acceptance of free currencies at a global level. Free currencies will eventually become legal, it's just a matter of time.
