I'm very disturbed by the idea that airspace NOTAMS can change after I've taken off. Why
should I or anyone waste their time looking at them on the ground, if they have to contact
ATC in the air as they approach the airspace, so they know what the airspace status is?

That seems to happen more often than one would think! Talk to the guys who fly the ridges in Central PA. When the POTUS decides to hop in a chopper and spend the weekend at Camp David, the no-fly zone around it covers a good part of the ridge(s). I am sure a NOTAM will be published but you will not know about it until you get visited by a black helicopter.
A similar thing happened a number of years ago when the POTUS was campaigning for reelection in OH. A NOTAM for a 'moving no-fly' zone was issued for the corridor between Toledo and Columbus but not even the ATC in that area knew, where the motorcade was at any moment. I inquired about it with Akon/Canton and their response was 'Well - do you see any Black Hawks circling you? No? Good - then you are not in it, yet!' We decided to pack it in for the day and fire up the grill.
