I didn't say it doesn't help. But, it alone does not really help for bad and long code, but you are correct in that it would be worse with the wrong indentation. Like you pointed out, the program could do the wrong thing if there is a wrong indentation where indentation matters which is one of my issue with something like Python. And languages with explicit exit scope tend to not have that issue while adding to the benefit of making longer code readable. Where white-space sensitive languages really shine on in my opinion are small codes, and that's where I think of using Python.
