The issue is that in practice it’s quite difficult to reliably get whitespace correct all of the time, whereas braces seem quite easy to get right. If you’ve ever tried cutting and pasting a code block in python you know the pain of having to manually fix whitespace. The same operation in a brace-delimited language has a much smaller chance of going wrong, as the only thing you need to get right is the endpoints of the cut selection.
