Point 1: Increase the local tax burden
Your response: "I don't think it's particularly contentious to say that a low-income person paying less in property tax means that a higher income person must pay more in tax to offer the same level of services".
This depends on the assumption that there is a zero-sum competition between rich and poor people. Every X number of poor people in a city, represents a subtraction of an equivalent number of rich people. Because rich people are presumably in a higher tax bracket, they pay more per person that do poor people. But there's no reason to think that there is a zero-sum competition between rich and poor people. That depends on complex empirical questions like the division of labour in the city, the availability of land and housing, if low-skill labour will attract businesses, and so on. And the fact that a poor person might not pay as much in taxes as a rich person does not make them a tax "burden" in any sensible use of that term - they may be net contributors.
