> why showing up on time is so god damn important

This is a matter of not wasting other people's time, it is a matter of respect. If you prioritize and plan accordingly, being prompt is usually quite easy. If you haven't done so, then you are effectively saying that your laziness is more important than your compatriot's time. Of course, this is only important when one of the parties has this view (it is some sort of prisoner's dilema, I think.)

That really only makes sense if they happen to be waiting on you; which isn't usually the case in most knowledge work.

I’m having trouble trying to find an instance of people not waiting on you at work (any work). Either it's real work with real consequences or it's busy work.

The thing is that there is plenty of work that isn't due on a tight deadline right now, but takes time to do. In these cases, why should my boss care if I decide to work noon to 8pm instead of 9 to 5? My boss doesn't care. I am my boss.

The measure of a good knowledge worker though is not being on time, rather it is productivity month over month.

If it's due at 5pm and takes all day, no one is waiting on you at 9am.

It really depends on how much coordination is needed on a daily basis, I think. In tech especially there are a reasonable number of companies that are fairly lax on caring what precise hours you keep, so long as the git pushes and bug triage keep coming.
