You don't want syntax because you don't want Magnetic Poetry kits, having to arrange very special "structure words" in very special places, and hope that "lines" make sense.
Don't think about (Lisp (notation)) -- think about the fact that the entire syntax is "this is enclosing box" (can easily be done with paper by putting smaller sheets on larger ones) and "this is the order of items within the box" (very natural to re-arrange these blocks). Lisp doesn't have lines, in that sense, and lines don't make a lot of sense in physical world.
Just to be clear, I'm not disagreeing about the fact that Lisp is a bit complicated to be first programming language _when writing text_. But its design is great for physical manipulation.
