Unfortunately with all these spectrum things, it's easy to see the extremes of the scale but less easy to say where the line should be drawn. If a homeowner has dug a big pit with spikes in it across their garden path and fails to warn legitimate visitors to their home about it, then yes, it's the homeowner's fault when someone going about their lawful business injures themselves in it. However the odds of something being that clear-cut are really, really slim. Trouble is that things like cracks in the driveway and security lighting, often it isn't a case of "can't be bothered to sort it out" so much as "can't afford to get it sorted out" or "don't have the capacity to sort it out", or maybe "have other much more important things to sort out first". Even if you're in a confirmed vulnerable adult/low income situation, and you manage to fight and shout enough to get some kind of grant to have it sorted out, generally (at least where I used to live) the council would contract-out such work to the lowest bidder, who is unlikely to make the best job of repairs and will sometimes leave the house in a worse state than it was in originally.
