If the Moon vanished, tides would become much weaker and Earth’s long-term rotational and axial behavior would change. The immediate effect would not be Earth flying out of orbit around the Sun.

This makes more sense when it is separated into cause and result. The cause involves Moon’s effects on tides, axial stability and night sky; the result is the pattern people notice. Keeping those two parts separate also prevents a common mistake: assuming that one familiar example proves a universal rule.
In other words, the surprising part is usually the surface appearance, not the underlying process. Understand the major physical consequences of a hypothetical Moon loss. That distinction is why the topic is useful beyond trivia: it shows how a familiar observation can come from a mechanism that is easy to miss.
