> I talk to people all day long, the kind of discussions you don't plan and send invites with an agenda upfront

For what reason? You say it's a total waste of time productivity wise. Imagine having this all the time, because it's how it looks like in an open space office.

This might be the reason why we are expected to work 8h/day. We simply waste most of our work time. It would be much better to be paid 2x more per hour and only really work 4 hours a day.

Also, working remotely does not mean my meetings have invitations or an agenda. You can call someone anytime. We have webcams on all day. I only have a calendar event if it is a planned meeting, like an interview with a new candidate, daily stand up, brainstorming session.
