Short Thought on Inerrancy

The Holy Scriptures, as originally given by God, are divinely inspired, infallible, entirely trustworthy, and constitute the only supreme authority in all matters of faith and conduct.

(from The Evangelical Fellowship of Canada's Statement of Faith; emphasis mine)

If God is so interested in making the originals of Scripture infallible, why is he so unconcerned with keeping Scripture that way? If you're going to divinely inspire the authors of the originals, why not do the same for the scribes and translators?
