This is a strawman. I never claimed one should use Liveview for all web work. I'm just saying people _want_ to do web stuff with languages other than javaScript. javaScript is only "the right tool" in the sense that it's the only one that's native to the browser. If they substituted javaScript with any of the other popular general purpose languages no one would be any worse off for it (not factoring in the ecosystem built around it). javaScript doesn't have any features that make it better suited for the web than other general purpose languages. It's _only_ real advantage is that years ago a decision was made to create and use JS (edit: ..in the browser) and we've all been stuck with it since.
