As someone who does a lot of work in Java (which lacks typedef), I feel the opposite. I don't like "stringly typed" APIs where everything is a String or int or whatnot - it's only slightly better than Object; you're basically giving up on typechecking. With generics or typedefs (or a willingness to create lots of classes), you can be certain you never pass an Id<Foo> someplace that expects an Id<Bar>.
