Yeah but personally I'd rather be less like China and their security state and just let people spray over each other's art projects. Assuming nobody gets angry about what is "their turf" or whatever.

I don't think we get to have much of a say in the matter. Technology and its authoritarian implications are a runaway train at this point.
