You might be surprised -- a minimalist mindset can extend toward computer habits as well. Also, just as he relies on society to provide him with essentials like food, so too could he rely on cloud providers like Google Docs to take care of his document storage -- though of course he would still own his Google account.
It's no stretch to compare Mimimalism to a thin-client computing design -- it is made possible by the existence of an excellent network of other person-nodes, and it reduces the emotional and physical "computational" overhead of owning things.
Also, in response to come other comments in this thread: to argue that he is parasitic requires the moral stance that using things you do not own is parasitic, regardless of the other contributions you make to society (including paying for the temporary use of those things!). Which is bollocks.
