You are misreading intent. When she is able to productively use computers as computational tools, she can have one. There has to be a positive to balance the negative.
That's interesting because if you set that out as a goal.. then what, right? What you'd like is on-going productive use once unlimited access is granted if your goal is balance. My inclination would be to be giving "homework" all the time, so the hours get split up somehow and aren't just spent of frivolous things once the privileges are acquired.
