Thank you for your candid feedback. I belong to those working in physics for decades. To avoid such misunderstandings in future, I improved a few lines.

One remark: the text is really meant to state that the specific 9 lines given do contain all of physics (and thus all other natural sciences).

The argument differs from "words and Shakespeare": the nine line describe nature exactly, within measurement precision. That is the central content of that page. It is not that physics governs everything. It is that those specific 9 lines describe all measurements, all observations, and contain all equations. This is a much stronger statement.
