Some people just don't like casual conversation and wouldn't initiate conversation on their own. If you have enough of those types, no communication wold happen. Ad-hoc conversation tends to be interruptive which is not desirable for people on maker schedules.

Either way, standups is just one communication strategy. Pick the communication strategy that works with the style your team feels comfortable with. There's rarely one solution fits all when it comes to communication.
