Interpretation is inevitable. There's simply no way around it. Neither is interpretation inherently bad or--perhaps more accurately--neither is interpretation inferior to some other option available to us. If we could magically divine precisely what everyone was thinking in some objective manner then, of course, we would be free of the need for interpretation. Except in so far as we would need to understand every individual movement up to that point in time.

"Literalism" doesn't work in Biblical interpretation or anything else. It's still interpretation, it just ignores the fact.
