Taxation is theft. "But who will build the roads" argument is really old and dumb, people are not some stupid monkeys who can't figure out things if no one guides them, there's nothing that can not be done privately and through voluntary cooperation (which is the same as privately). Roads, military, science and so on - all of it can and is done privately around the world. Government is exactly why Bitcoin was invented - you can't trust people with power and believe that they will do as they've promised, and even well-meaning leaders do stupid mistakes that cost billions. Just like Bitcoin have decentralized economy, some day people will decentralize power to the point when every individual will be independent from others.
I think you are missing the point why taxes are being collee for every indiw that contributes tk the community. We cannot force an private organization or even push the responsibilities of the government and even purging non-profit organizations to fill the needs of the community, we can say that the taxes are verg essential for every infrastructure, innovations and any public or provage services that we have recieving, taxes are the fuel of the country, it must be maintained.
