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!
just because we haven't figured out how to organize human communities in such a way that they build roads, hospitals, schools, support to those who need it. ( modern society ) without the need for a central authority, doesn't mean it is impossible.
the bitcoin model could hold the key, replace the central authority with some kind of AI that everyone gets a say how it thinks and acts? tax may still be the way, but the at least the rules would serve the will of the majority by designs.
crazy tough question...
