Because you get very little repeatition of notes, rhythm, or structure that you get in rock/pop.
I play in orchestras and in large wind bands. Some of the easier pieces, the music is an aide-memoire since you get to know it after a few rehearsals. But you don't develop that level of familiarity with more complex works, plus as already noted, there are a vast number of articulation, dynamic and performance instructions, as well as notes and rhythm to worry about, plus other performance guidance notes, cuts etc. Typically you get maybe 4 or 5 rehearsals, do concert, start rehearsing new set of music...
I don't yet play bass in any group. When I get round to that, it is likely to be jazz-ish probably. Since I don't currently know any bass music, I'm anticipating using a stand, which I do not see as a problem. Maybe over time, if I end up developing a core repertoire that is aired regularly, that requirement will fade. Don't know. I don't see it as a big deal.
One orchestra I play in has a partially sighted player. He has an A4 sized tablet. He gets his music scanned and then video reversed so that white is black and vice versa - he can see this better. He has a pedal to control scrolling.
The main point is surely that what matters is the end result - if it's a decent performance, what's the issue?

Orchestra: fine
Imagine Muse or Metallica with music stands.
No.
