I mean, is it that hard to imagine that someone doesn't have a knob next to their bed?

Also, I've maybe seen a speed control knob for a ceiling fan a few times in my life in the US. Here it's all pullchains, or more recently "smart" bullshit.

I am European and every ceiling fan I have used has a wall mounted knob. It is very convenient. Could be a regional difference.
