Some counterpoint.
Re 1) That all depends on your commitment and amount of self discipline.
Re 2) You have to have 2 failures to lose a week. Your you main storage AND your backup drive.
Re 3) I don't get your point. If one fails you replace it.
Re 4) True, good idea to grab that HD if you packing to leave because of a hurricane.
Re 5) What could possibly go wrong? I repeat, even if you have "the cloud backup", you still need the physical backups.

Regarding all the points, you need your DR copy when your primary (working copy) and your on-site backup fail. This can occur from fire, theft, power surges lightning strikes, floods and other natural disasters, but also virus, ransomware, malware or operator errors or accidental deletion where an issue is propagated from the primary storage to the backup. Happens all the time. Doubt that? Just read the forum - happens regularly.
As to number one, it all depends on how much time you’re willing to waste. You could ride a horse to the bank I suppose for a leisurely trip.
As to number 3, taking drives in and out of service (bringing down and restarting a spinning disk at a later time) is a classic failure mode. You may run a disk constantly for years, but bring it down and restart it at a later time, and it fails - a well known failure mode that professionals are aware of. At Y2K, the major storage companies instructed their clients NOT to bring down their storage for this exact reason - many disk failures occur on start up
As to number 4, in most of those failure scenarios, you don’t have the opportunity to grab the disk and run. In several recent forest fire and hurricane disasters, both the home and the banks and offices in the community were destroyed. Suppose, worst case, my house burns or is destroyed by a tornado or hurricane. All I need is a phone, tablet, laptop or the business center at a motel to get ALL my data, including insurance policies and images of everything in my home to file a claim. and of course, I have all the images that I spent thousands or tens of thousands in equipment and untold hours to creater. Of course, if I’m working, my company’s IT department has taken the steps I mentioned, so I can access it and continue working. Or if I’m self employed, I can continue working with ALL my data, wherever I am.
You absolutely DO need a local backup, but you also need a 3rd off-site DR copy, and the cloud is the most robust method to accomplish that. I’m just providing you the professional best practice procedure. Whether you decide to follow that standard is always up to you as is the value of your data.
