For all practical purposes

"For all practical purposes" is an idiomatic expression that means something is effectively true or will have the same outcome in practical situations, even if it may not be technically accurate or entirely precise. It suggests that, while there might be some nuances or exceptions in a theoretical sense, those details are irrelevant when it comes to everyday use or real-world applications. Essentially, it indicates that for most intents and purposes, a certain statement or condition can be accepted as valid or applicable.
