Isn't it easy to just auto format it?

And I love that people love indentation based languages so I show them a file with some spurious tabs to see how they feel about indentation causing silent errors.

Sure but even with no code indentation at all, an auto-formatter can easily indent everything for you because of the braces. If you have poorly indented code in a language like Python, you're on the hook for indenting everything yourself. And as a bonus, the code won't even run until you do.
