in a democracy you vote for parties based on their taxation and other policies, and the ones favoured by the majority of people (or whatever system is used) are implemented. what you see as being involuntary theft could also be seen as belonging/contributing to the society in which you live, based on democratic principles. in a participatory democracy you would participate even more directly in political decisions and policies that affect your life. of course no one wants to give up their hard-earned money to be spend ineffectively or on the wrong things. this is why citizen participation, in all its forms, is important.
