Sure, insofar as you need a medium. However you can do great art (graphical, literature, etc) with minimal (technical) medium/craft, e.g. a pencil. Or just your voice; speech is a medium and a great example of a craft requiring significant and non-obvious skill to do well with despite its apparent technical simplicity.
Would you say, then, that a medium, not necessarily a craft, was necessary as a vehicle for art...and that that medium could take the form of a craft, skill, or both?
