A subtlety of point 2 is that not all products or services benefit from multiple deploys per day. If each deploy creates work or risk for the customer, then beyond some point, frequent deploys may be harmful. Your customers may have more valuable things to do than consume or help QA the latest increment of your offering. Separately from deployments, in some less-than-ideally run organisations, management may whimsically change its mind about what the number one priority is from day to day. Two-week sprints can shield the delivery team from this, by acting as some kind of low-pass filter on thrashing priorities, to create space to get a few things entirely done.
