They said the exact same thing about Bitcoin, that it's just an imaginary currency and doesn't exist in reality. It's a way of discrediting it. I'm not defending ordinals, I don't use it, just trying to look at the argument.

Casey is right, you'll get brain hemorrhage if you keep dwelling on it. Go outside, touch grass

If it is a seperate protocol, then why their tx's are on the same blockchain?

I hope we can be vigilant against such scammers that promote changes to bitcoin.
