If you don't have it at the beginning of the day, then you're putting a hard gate on flow. This phenomena is well known, and the disruption of having a scheduled event mid-workday is significantly larger than the time of the disruption. Everyone is going to fade out of their work long before and won't re-engage for sometimes after.

As to scrum exposing cultural problems, maybe that's true, but in some cases scrums are a clumsy attempt to solve cultural problems (as I said in another comment, agile was the failure mode for orgs stumbling with "waterfall").

Terrible progress visibility? Let's have a scrum! No team member communications? Scrum will fix it! People sandbagging or not doing their work? Don't worry, Scrum will save the day!

On good teams we all know what each other is working on. We're all aware of the codebase. We see the commits. We are available when someone has a problem (and people know who is a good person to asynchronously ping when they have a problem in specific domains), and are open to the reality that everyone is imperfect and doesn't know everything. On good teams scrums serve absolutely no value, and are a redundant waste of time. On bad teams they are an attempt to bandage over all of the lack of those factors.
