Now is probably the right time for the NATO Response Force to come out from under a stone and swing into action.
And do what exactly? Imposing an NFZ would be viewed as an attack on Libyan sovereignity by Ghadaffi loyalists, and probably would not be welcome either by the opposition, or the wider maghreb. Even if there is some minor misuse of the loyalist Libyan Air Force against civilians (where are your sources TEEJ?), the situation has not yet got even close to a UNSC resolution. Russia would almost certainly veto any proposed resolution.
Or are you imagining that NATO would abandon its statutes and take pre-emptive action, even though there has not been an attack on a NATO member?
I agree with the rest of your post though - the idea that a carrier would be useful here is laughable. If the UNSC approved, or if NATO really did need to impose an NFZ over Libya through a direct threat to a member, there are plenty of unsinkable airfields nearby that can accommodate more capable aircraft, more quickly and less expensively than any solutions NATO could deploy from a carrier.
