How they supposed to pay for infrastructure, defence schools, hospitals etc if there's no taxation?

For a country the size of brunei or Kuwait it is possible to have no taxes, but this is also dependent on state owned resources, and the benevolence of the Government. Having no tax revenue is a untenable situation for a government.

How they supposed to pay for infrastructure, defence[,] schools, hospitals etc if there's no taxation?

The government has no business paying for schools or hospitals. Granted, the government has no business owning an oil field, either--but I'll be generous and let them have one so they can pay for the armed forces, the judicial system, and the roads.

The benefits of having absolute zero taxation are enormous. Freedom takes on a whole new dimension when you are free from government agents sniffling through your accounts.
