I don't understand your argument. Let's say someone learns a proper programming language like Python, creates some spaghetti code (as any beginner will do), and that gets used by the business. How is that any different than a spreadsheet that does the same?

Excel's strength is that people are actually productive enough to start using and make something useful. Whether people make substandard houses with a hammer isn't really the tool's problem. Being too difficult to pick up is.

You might argue there is some quality bar that should be met before a creation is put into production, which is fine, but that's independent of the tool used to make it.
