It you take my property via threat of violence (coercion), that is thievery. School children understand this. So I'm sure you do as well. Taxes aren't voluntary and if you do not pay them, you will be jailed. If you resist being jailed, you will be violently detained. If you respond with violence in kind, you will be killed.
I don't care if you think that the ends justify the means. We're just discussing definitions.
If your landlord demands you pay your rent, is that thievery? Because that’s essentially what tax is
I own a house. I bought it off someone else who bought it off someone else who… go back 40-50 years ago, a property developer bought a farm and subdivided it… and the farmer bought it from another farmer who bought it from another farmer… and it all goes back to this massive farm which was subdivided into smaller farms… and that massive farm was originally a government land grant… and before that the government owned it… and the government got it by stealing the land from the indigenous people
The government land grant was made subject to the condition that the recipient paid taxes. And since you can’t give better title than you have, the same condition passes on to all subsequent purchasers. If the government has no right to my taxes, then I have no right to my house
If taxation is theft, then property is too. But if property is theft, then calling taxation “theft” is like a small time crook complaining a bigger crook robbed them
When the first ape walked upright, which government was there to tell them what land they could have?
