“Bottom lines is that your property is NEVER actually yours.”
That means nothing is “yours”, your car, your groceries, etc. But yet you can sell your house, and the govt can’t if you pay your taxes. Also, this isn’t a federal matter, it’s a state matter. If you lose your house for not paying taxes, another individual ends up with it. The state of Montana doesn’t keep it or own it, it just sells its lien.
