You do you, but I found most of the advice highly useful, and actually enhancing convenience.
Don't use hotel safe or under the mattress - yup, good advice, seen that before, and definitely need to think about valuables & passport storage at all times anyway.
Book in advance and hand them copies of addresses, docs, passport over the counter - yup, great advice, also means you have a 2nd copy on you, which can be a lifesaver if your phone or primary docs get lost/stolen.
Checking maps and orienting yourself to the surroundings is something I do anyway just to know where I am, and actually allows me to enjoy the sights better since I'm no longer primarily occupied with wondering where TF I'm going.
Having actually walked the exit routes would be incredibly useful in a wide variety of emergencies. Both being able to exit from memory if something happens, and also knowing that one exit is actually blocked. It'd really suck to die because you went out an exit and found it blocked, but could no longer access the other one... I also find that, although I haven't done it explicitly (I will in the future), it's often just handy to know other routes to get to/from the outside - they often wind up being more convenient, especially when carrying stuff.
Asking for 2nd/3rd floor room sounds like excellent advice, especially in unknown foreign areas, off the (vulnerable) ground floor but multiple escape routes in fire or attack. Self-rescue by jumping or down-climbing a bedsheet rope is still very possible in ways that it isn't on floors 4 and up...
Etc... I really don't understand not only rejecting such good advice from a clearly knowledgeable expert, but also taking the trouble to write a post advocating that other people also ignore it. Seems you're insecure in your willful ignorance, and want others to join you; please stop doing that.
