1) because of the privacy violation requirements to enforce it and because it encourages non-production I think some tax like property tax and sales tax are good Otherwise you are using roads, getting other government services for free like a criminal (taking/using something for nothing) I'm not a criminal
You might not be a criminal according to the gov but you might be aiding criminal activities when you justify taking money from people without their consent. You don't know if the money you pay in taxes are going to be spent on wars in the middle east or drag shows in Europe. If people had the choice to monitor and vote were their money is spent instead of choosing people the current system may fail.
