I'm not arguing for time sheets, or even any form of time tracking. Just that as a team, if we agree to show up to the office at a time, and someone isn't there then, you'll have feelings about it.

The part about teams that operate via timesheet is a bit of a stretch, imo. At least in larger orgs, I don't see the "need" (read: keeping middle-managers employed) for time tracking ever going away.

While I agree with the sentiment that time tracking is pretty useless, I don't think it's going to stop.
