If you think daily stand-ups are working great for your team -- and, more importantly, the team thinks that too -- stick with them. If you're curious what life would be without them, then abandon them for a couple iterations and objectively observe what happens.
Agility is a good thing, no doubt, and the Agile Manifesto isn’t unreasonable. Compared to a straw-man practice called “Waterfall”, Agile is notably superior.
