I understand the point you're making, but even tapping off an existing fuse connection involved running a different wire, even if it's the same gauge it won't have the potential to overload that existing wiring. You may never put enough load on that fuse connection to pop the fuse unless it shorts, meaning there is plenty of power there, but you could overrun the intended use of the gauge wire thereby causing excessive heat and degradation of the wire or insulation on the wire... which can cause the short, perhaps arcing to the frame and the fuse pops... etc etc.
As I said previously, it's likely not going to actually be an issue. You'll probably never run into that situation but you can't run into it if you run your own wire. Also to your point, using a dedicated power block would probably be the actual solution. Wire a relay in to actuate off the accessory power coming on from a dedicated power line from the battery. 100% see your point. The original intent of @securityguy's comment was, as I understand it, to say don't run electronics off a wire that was designed to power only x things. There's a predetermined amount of draw that wire/fuse/etc is made to do.
Haha, there's no point in fighting over it.
