People really really reallllly want to believe there are laws of grammar/language like there are laws of physics and it is honestly kind of hilarious.

The power of language comes from there being no rules or laws, language is just the sum of what people choose to write and say. You can impose patterns on what people tend to write and say, but ultimately it is no different than looking into the night sky and deciding a couple of stars makes the shape of a lion and believing you have determined something fundamental about those stars.
