Any harm in disabling all these settings?

I wondered this too. I have this picture of someone turning a light on and off every second instead of just leaving the lights on (or tapping a lamp again and again to change the brightness). Does this burn the bulb out faster, or is this just a myth? (many sources I know have claimed it does, while others have claimed it doesn't). Since a lot of power saving features on laptops turn the display on/off up/down, wouldn't that be the same thing? Or does this only apply to certain types of lights/electrical components? I imagine almost any kind of change would cause some kind of wear (like bending a book open and closed over and over again, though I guess keeping it open might cause the pages to wear/stretch/break as well).

The filament in a "regular" lightbulb is going from room temperature to somewhere in the region of 2000C every time you sitch it on, the physical expansion and contraction of this means that a lightbulb being turned on and off repeatedly will on average break a lot faster than one left on. However trying to relate this to the internal workings of a CPU is a pretty big jump

It's not the same as a light bulb. If you want to equate it to that it would be more accurate to say a light bulb on a dimmer switch vs full on/off switching. Even then it's not the same. All those fancy power supplies and devices on your high end motherboard are delivering far cleaner power to the CPU than a light bulb gets from your utility company. The "sudden" ramping up of speed/voltage is also exactly why Intel factored in vdroop into the circuitry.

I think the more important factor here is that the inside of a CPU isn't reaching 2000C .

That too... What it boils down to is that there are a heck of a lot more differences than similarities.
