IMO CoffeeScript exists because we can't really avoid JS for web apps. But avoiding PHP is pretty straightforward - you just use python, ruby, or whatever.
In theory, yes. In practice, it's not so simple. Most developers using php do so not by choice, whether due to legacy code, or requiring php's ubiquity, or what have you.
You can't use ruby or python to build wordpress plugins, for instance.

Good point. I can see where something like CoffeeScript for PHP would be useful.
