Why is this not a global armchair sort of affair? Staff the site with a tech as needed, but otherwise automate the whole deal and observers can queue their requests which will get filled as god/weather/orbits permit?

First, some telescopes do do portions or all of their observations in queue or staff mode, where you just give them the required objects and weather conditions. Just not all of them. I think most 8m class ones will have a mixture-- if your proposal wins just 1 night, then maybe it goes to staff, but if you got 10 nights you get to do it yourself.

There are a few reasons. First, lots of astronomers do not trust anyone but themselves to deal with the data (and this is a reasonable distrust as every single telescope has a unique 'feel' and quirks)-- so they want to be there to do reshoots if necessary.

Another is that it's not entirely schedulable, like, if you queued up the whole year's worth of observations (this is what you do, twice per year you can apply for time, some telescopes once per year), and then everyone's sent you their absolute best case requirements and you end up not being able to fulfill them on time (because maybe there's a big volcano in Iceland that changes the atmospheric transparency for 4 months), then its inconvenient and the astronomers feel gypped that they won the time but didn't get the observations.

Astronomers prefer being told: okay, you get 8 dark nights, but if there's a storm, your SOL. But this is ok because you frequently have all your buddies on Skype at the dome, so when you say "shit well the seeing is too bad to get these spectra" your buddy says "well I have a bright night project we can probably do through the clouds." This is how a lot of observations and projects that can't win time on their own get their data.

A staffer will know how to take your observation requirements, wait until the conditions are right and get exposures of x object at y wavelength for z time.

An astronomer will be able to, on the fly say: well our original plan isn't going to work, but I know that at this time in winter we can see Draco from this latitude and my friend was doing a project in Draco that isn't too hard so I'll just snap that while I'm here.

That and most people like going to observatories, best business trip ever.
