The point is still about ergonomics though. The AST for Rust or D is still complicated enough that you typically won't do the kind of thing you might do in a lisp just due to startup cost. Lisp because of it's extremely limited syntax makes it considerably easier. The sorts of things you'll feel free and capable of doing in a lisp macro are ergonomically harder to do in a Rust or D macro.

You might argue, quite convincingly, that Rust and D have valuable ergonomic barriers to doing some of those things since macros have a non-trivial cost in your codebase regarding complexity and readaiblity. But the ergonomics of a macro is Lisp are pretty close to the optimal for ease of use.
