While I completely agree with the decentralization aspect of bitcoin, I fundamentally disagree with using it to avoid taxes. Society NEEDS money to fund things that the public uses, roads, bridges, schools, hospitals, firemen, police, parks. Taxes are the only way we can pay for these things, and while very wealthy people avoid taxes all the time, that doesn't mean we should. Society would fall apart without the resources that come from taxation. The wealthy people who avoid taxation will eventually fall, but it may take a long time for that to occur. We cannot and should not follow their lead and dodge as many taxes as possible, we just need to make them pay their fair share.
