In practice since most taxation is just used to pay for goods and services the population wants there is popular support for taxes. In places where taxation is more outright theft, tax avoidance is rampant.
1. Consultancies, accounting firms and senior government make huge amounts facilitating it
2. Enables evasion by the rich and punishment of the poor!
3. We don't realise how much tax we're paying on stuff
