Unless I've misunderstood you, I'm not sure that's a strawman argument. I'm not arguing against the original point! I'd like to have better representations than just plain text. The fact that our current input methods are holding us back is more a fact, rather than an argument against trying to fix the situation.

It's the friction of entering those other representations that's the problem.

The use of an interface drops off in greater proportion to the difficulty of using it - Nev's law

(IE, if a user interface is twice as difficult to use (takes twice as long to do things or takes twice as many steps for example), then it will be used by much less than half as many people.)
