This is basically an appeal to authority. You haven't explained what property of the Raspberry Pi 4 means that a tiny heatsink is sufficient. Why can't I just r

  Because you can see in the graphs that the bare pi doesn’t get that hot. If you allow just a bit more heat to escape you push the graph down to where the peak sits just below the throttling point. For home/hobby use this doesn’t matter too much but you typically want to run as hot as allowable. It’s a win-win since small heat sinks are cheap and don’t have any moving parts.

    Running 32-bit raspbian... Try that with a 64-bit OS, running 64-bit compiles/etc. I have a huge heatsink on mine (40mm cube), and even without the overclock it will crank up to 80C doing long running compiles. Running it at 80C for an hour or two, the temp of everything on the board starts to approach 80C. Touching the usb ports at that point will give you a surprise. So, I added a small 20mm fan, and set the profile to kick on at 60C, which generally keeps the soc thermals in the 60-70C range. No throttling, and still no noise because with that large of a heatsink it doesn't take much air to cool it. Add in a couple hundred Mhz of overclocking and that fan stays on pretty much all the time.
