The fact that wizards use magic for pretty much everything, there is no real point to use physical violence since magic spells do a lot more damage and are more effective.

It's not about opinion, it's about how it is in the Harry Potter universe. In the Harry Potter universe, physical violence does happen magical or no. There is no evidence that they relate physical violence to muggles, so please don't act like it is cannon based on opinion. If you have hard evidence of it being mentioned by J.K. Rowling in the books or otherwise, then it will be considered cannon.
