That latency is time stolen from the other people who are already on transit (or waiting in line to get on) who get there later. All this latency is the type of thing that makes people want to quit using transit and just get a car. (and then build more roads to deal with congestion - though road users often have more options to avoid this latency and overall generally go faster than transit despite the congestion - remember it is end to end trip time that matters not time to get through a bottleneck)

Not really a comparable thing versus the morning/evening rush every single weekday when forcing people in-office. It's the scale that makes it an issue, 1000s of people is nothing and more of an occasional spike.

See how London deals with toob stations for pride, for example, by closing and controlling some, exit only periods close to the event, open ticket gates, etc.

Haha, absolutely! Just to generalize, those thousands of people can also watch the match by streaming, right? It's all about remote versus physical activities.

We can't shift everything into remote mode. However, we don't need to hustle into physical mode every day either. Yeah, yin yang complexity, balancing everything out.
