The point of language is to convey meaning. Grammar is less important than what the speaker wants to tell other people.
If this sentence, in context of a larger conversation, has meaning to the people listening to it, then congratulations! Rejoice, for communication has been achieved! Whether it was grammatically correct or not is irrelevant, because the intended target understands.
Language changes over time. Nobody just decided to come up with modern English one day and it caught on, it’s a gross pot filled with words and grammar from many other languages (some more melted than others, so not really a melting pot), and mostly filtered from a language nobody speaks anymore.
So having what are essentially arbitrary rules that dictate how things must always be for that language is already pretty dumb to me.



Yes but my point is that if it conveys meaning to the intended target, it’s irrelevant.
Plenty of sentences, out of context, have no real meaning. The example in OP is one that could have meaning in the right context, which would be understood by its recipient
