Some people like braces, like me. It doesn't matter at the beginning/middle of a code block much, but the clearly visible terminating } is what does it for me. I need that.
If every whitespace significant language had strict formatting standards, shipped with a formatting utility (e.g. gofmt), and actually enforced formatting standards everywhere (including stuff like number of empty lines between functions, etc...), then I would be on board with no braces and whitespace significance. Until then, the inconsistencies you run in to in whitespace significant land just don't work for my brain.
Then, some people hate braces and love whitespace significance. Cool. doesn't matter. the end.
