Because in Discord you hop into an audio call and you're there for however long you want to hang out in the room. People can come and go from this room, but the room is persistent. In a job, you're going from meeting to meeting each with different attendees and stakeholders. You might have been on top of it in the morning for standup then 3 hours and a head full of code/spreadsheets/whatever later when you're discussing tech debt with other people you forget to unmute until your portion of the meeting comes 5 minutes into the start. Push-to-talk certainly helps, but if you're frequently talking in small meetings (say 3-5 people) then PTT becomes more of a hindrance than a help. Personally I just have a headset with hardware mute functionality and a big red circle showing me it's muted. It remembers its muted status, so I just mute it by default and default my OS to use the headset's mic. That way I know quickly and easily when I'm muted and when I'm not, though even then I have small mistakes in the mornings when I'm tired. Over time I've optimized my meeting workflow because my company has gone all remote and I'm in a lot of meetings.
