Instead, I am arguing that property taxes should change based on their reason for existence, funding the local government, and not be used as a tool to deprive people of the ownership of their property.
For example: A storm blows over a big tree, which severely damages the local elementary school. The school has been underperforming anyway so we need to hire new teachers and outfit the classrooms with better technology. All of this means the school needs more money. Local government officials decide that this may be funded by an increase on property tax. This is the reason that property taxes exist, so the argument to raise it here may be good, even if the value of my property hasn't changed.
As a different example: A big tech company comes to town and hires many thousands of workers. The high paid tech workers want houses in town, and the additional demand drives up house prices. Why should I pay more taxes? People with more money may want my house, and they are free to offer me their money. Using their demand for housing to justify asking me to pay more money or lose my property is unreasonable and unethical. This is what I'm arguing should not be done.
