they make you pay taxes without consent but it doesn't give you a say and people who pay no taxes directly get as much say as you, so they will vote for more money from the taxes governments used to be small, placid things that did mostly important work and now they are trying to replace everything with government, and everything is going to shit
We're not really represented either. The ratios of Congress-critters to citizens are so high most people don't know their representatives, and the representatives certainly don't know those they supposedly represent. So it's essentially taxation without representation as well.
It cant be like anything we have imagined before, must preserve human freedom, happiness, and common defense, be incorruptable, etc, etc. We might already have it with bitcoin and just can't imagine the implications of hyperbitcoinization.
