Passports/citizenship: Although most people will see a passport a sa travel document, you could also see it as a certificate of ownership. In many countries it is illegal to have multiple passports which supports this argument.
Try resigning from the United States. It’s very difficult. Also, passports and border patrol have been used to prevent people from leaving a country in order to exploit their labor, and slavery:
> During World War I, European governments introduced border passport requirements for security reasons, and to control the emigration of people with useful skills. These controls remained in place after the war, becoming a standard, though controversial, procedure
Lastly, if you do not comply or pay taxes to your owner, you will be taken by force and sometimes with the result of injury of death.
Income tax is even less coercive than previous forms taxation, where people were taken from whether or not they could afford it. With income tax, people who do not work do not pay it. In fact many people who do work do not pay income tax.

If you earn “passive”, it still happens, but rates are a lot lower

Sharecropping taxes are income taxes. There weren’t formal income taxes because peasants didn’t have incomes. They paid a tax to their lord that was fixed as a function of the productivity of the land they farmed.

I'm not going to argue for the hyperbole of us all being slaves though.
