If we interact with spaces primarily as a series of disjoint divisions then we tend to think our actions on the world can be contained without side-effects. In any busy city you can see the store owners and proprietors manicure the space directly in front of their building. Planting plants, brushing the pavement, creating a sense of mood and ambiance around their particular restaurant. And that obligation stops immediately at the margins of their property line. Of course this just pushes negative patterns to the edge where pressure builds up more strongly.
Simplicity, linear surfaces, boxes, walls. These patterns fail because they hide but do not eliminate side-effects. In fact they magnify them. It is the lack of synthesis between spaces, the lack of free movement between them that makes pressures build up. If you can’t understand that you could share a ride with a new friend to work, or that kids are constantly vandalizing your street because they used to exhaust themselves instead in a wilder more abandoned overgrown forest, then you tend to work against opportunities, you end up spending more energy to get less.
