I’ve found that whenever I think “why don’t other people just do X” it’s because I’m misunderstanding what’s involved in X for them, and that generally if they could ‘just’ do X then they would.

“Why don’t you just” is a red flag now for me.

Not always. I love it when people offer me a much simpler solution to a problem I overengineered, so I can throw away my solution and use the simpler one.

Half the time people are suggested a better way, it's because they're actually doing it wrong, they've gotten the solution's requirements all wrong in the first place, and this perspective helps.

this applies to basically any suggested solution to any problem.

"Why don't you just ..." is just lazy idea suggestion from armchair internet warriors.
