OMG. That is extreme. I would not want to be the one to move and reposition that a lot! Your wife must be majorly paranoid and/or extreme with fear of heights.
I am somewhat the opposite. I rock, mountain and ice climbed a lot in my relative youth. So I got perhaps too comfy with heights and what many might consider precarious positions. But some advice if I may: a lot of accidents happen due to being unaware of surroundings and issues developing (footing of yourself and ladder, what and how you are reaching, picking things up, etc). It is best to be alert and aware of surroundings and dangers ... not walk off a roof edge while wrestling parts etc. I would NOT want the ladder with the cage and net. If something started to slip it would be very hard to reposition and compensate or hop off. So it might make small mishaps from not so high much worse if it came down or you badly slipped while overreaching etc.
I have a small footprint CA hillside home (downslope) where a step off the rear would result a 4+ story fall and one would, on landing, bounce and roll down a 45 degree hillside for up to 400 yards (ok, you would not go that far but you would be done long before). The house is somewhat like a treehouse and is a challenging place to work on ... even doing minor stuff like siding and painting can be an adventure to setup etc. I use pump jack scaffolding and sometimes climbing equipment (harness, rope and shock absorber) IF I am reaching and spending long time in location (attention tends to wane in long hours and mistakes can happen) where I might slip. Climbing equipment help with safety, but do not forget if you use it, that if you fall that the impact hits with a big shock. So you usually better have a *shock absorber* in line along even with a springy climbing rope AND enough line out to absorb shock while being well connected from a higher position where you do not "pendulum" in the fall. Plus you need a plan on how to get down if you ever do fall. I would not want to be dangling from my back like on some of the construction crew arrest equipment (crew is supposed to rescue?). I rig my harness that I tie in where I can belay myself down after any fall. Make sure you know how to use it and test the rig in controlled circumstances vs assuming it will work. You need a self-rescue plan unless your wife or neighbors can save you (hauling up is HARD !!), or you want a long, humiliating, and uncomfortable dangle time until the fire department saves you or until buzzards finish you off. In my case, I know that I am on my own after any fall since once I dropped something heavy with a horrible crash and my wife never came out. I later asked her why she did not check on me. She replied with something like, "You are are always making loud and dangerous sounding noises ... I would be going out every minute if I did so when I heard stuff. " Hmm. She also knows that I have plenty of painful death "accident" life insurance .... Ironically, accidental death insurance (distinct from insurance from death due to poor health) can be fairly cheap. But if you mountain, ice, or rock climb, or work yourself on the hillside home, try to avoid telling the company that sells the insurance what you do. My former climbing partner mentioned his hobbies and said the agent was quickly out the door and he was not offered a policy! I told my wife that if I die of a heart attack, then she should push my body down the hill since I am worth more if I die in an accident.
