Something interesting about your three pictures, there's very little concrete or asphalt in them, just poor old plants that we did not spend enough effort protecting from other plants. Myth of wilderness?
A typical knotweed patch that I see here in Scotland is in a disturbed urban area, for example by the railway. While it might be displacing a native species that takes over ruderal sites, e.g. blackberry or gorse, it still performs its functions of urban greenery - makes habitat for birds, cleans up the city air a bit, covers up trash on the ground.

Some of the roots I've dug out had about 8cm diameter and they were tough stuff. No you don't want this stuff even in urban wasteland. Or growing in railroad ballast where it's can cause a very expensive clean up operation or destabilize the foundation of the railroad.
