Why placeholder text is deliberately unreadable
The point of Lorem Ipsum is that you cannot read it. Real copy pulls attention to itself - a reviewer starts editing the words instead of assessing the layout, and a stakeholder reacts to the message rather than the design. Pseudo-Latin keeps everyone looking at spacing, hierarchy and rhythm, which is what the placeholder stage is for.
The text is not random. It comes from Cicero's *De Finibus Bonorum et Malorum*, written in 45 BC, and has been used by typesetters since at least the 1500s - the standard passage begins mid-word at *dolorem ipsum*, which is why it opens with "Lorem". It has survived because its letter frequency and word-length distribution are close enough to English to look like real text at a glance.
That similarity is the functional requirement. Filler made of repeated identical words would produce misleading line breaks and unrealistic text density, so the layout you approve would not match the layout you ship.
