Knots in general are a harmless and occasionally useful pasttime for many people. In fact I have a length of rope under my desk I will occasionally pick up and practice a few useful knots in just to keep them in my muscle memory. It's similar in many ways to people who solve rubix cubes or play with fidget spinners.

It somehow reminded me of this: (How to open a door - Finnish instructional video from 1979) https://www.youtube.com/watch?v=Wof0xPUmW38

You could also say life is too short to waste time retying inferior drawstrings. If learning the knot takes 5 minutes, it seems like it could easily save you time overall.

The Ashley Book of Knots has 3857 numbered entries. Each is suited to specific requirements. Some are just fun or decorative. It can be a hobby to learn more.

Domain people might have a dozen knots to get their job done. I just took a swift water rescue class; we got by with maybe five total for our situation.

Tying shorts? Maybe two or three are best suited.

I got through an entire day yesterday in massively oversized gym shorts, by simply forming a standard loop, and wrapping it _twice_. That extra friction (the second wrap) has worked for years on shoes, boots, and, very large shorts

I will not be learning a fancy knot because I have no need

Eh, knots are a source of joy.

Min-max all the things! Overengineer everything!
