Having mandatory, is NOT the same as coercion.. b/c a large majority of the people do NOT need to be coerced to follow rules of their own making and a society of their own choosing and a community in which they chose to live... I would NOT call that coercion.
If I resist paying taxes, the government intervenes with the threat of force. Threat of force is the very definition of coercion.
If people are really choosing to make rules to provide welfare, then they can skip the intermediate step and chose to provide welfare. Everything else is coercion.
That is why this back and forth communication with you is getting NO WHERE - b/c you keep insisting that your being part of a community is coercion... and you give way too much weight to this coercion aspect - to the extent that taxes are mandatory and a part of civil society, and almost anywhere in the world has some taxes.. though there is variation. If you are an American (or another western country), you have won the lottery, b/c you can move almost anywhere in the world with your passport and find some haven that has little to no taxes. What country are you from? You seem to want the benefits of being part of a community, but you do NOT want to pay into that community's rate of taxation.
why being part of a community is coercion, what dont you understand...
