I don't really have the energy to respond to all your points (but thank you for making them, they've shown where I was unclear in my writing, or made assumptions that weren't obvious), but I wanted to mention one thing: > This whole thing could be bypassed by arguing that these types of improvements should be paid by property taxes This is pretty much the core policy that Georgism advocates for: "Henry George is best known for popularizing the argument that government should be funded by a tax on land rent rather than taxes on labor". The rest is just a way to provide economic/justice based reasons for this policy.
