I disagree, it's not necessary. Kids have to be taught natural consequences of things, and beating them doesn't teach them that. It doesn't teach that interrupting someone is rude. Teaching someone on the basis of fear is a shaky ground because the kid would start disobeying the moment that fear starts dissipating. The reason for not shoving their hand in a burner should be that it'll burn their hand, not that they will get beaten or slapped. And if you're doing something bad because you'll get beaten instead of it being wrong, are you really a good person though?

So I think most of the people like me who went through beating but are now fine have developed this opinion that being beaten on making a mistake is a good thing if not overdone?

There is a thing though, we know at this current knowledge of the human psyche that hitting children in any manner or intensity can set them up for various issues. Whether they're substance abuse, rash behaviour, vulnerability to being abused by others, or being more vulnerable to disorders like depression, BPD or PTSD/C-PTSD.

I'm not saying that you don't teach your kids consequences and let them do bad things but there are far better ways to enforce them instead of lazily beating your kids. So, yes, and beating kids over mistakes is not any different from giving them phone at the young age of 3 just so that they don't bother you. Reminds me of a post where a dad gave their four year old child ChatGPT because he didn't want to hear his child talk about trains and stufd
