Tax system is necessary for human community, isn't it? I thought it was common knowledge.

Whether taxes are spent properly is a different issue, isn't it?

Those who survived without tax can not say other people do not need tax support. If they say so, they don't really need bitcoin as well, as they don't need community.

Humans are social, by nature. Bitcoin will have to go well with tax. But, it does not necessarily go well with fiat!
