> A woman, even one 42,000 years old, is not merely an "opportunity", she's an autonomous person with human rights. But apparently the whole idea of the Enlightenment is naive.

Nope. Her life effectively ended 42,000 years ago. Her unfreezing would basically be her afterlife.

Everything she ever knew would be dead and gone, the world would have completely changed. If we could figure out how she survived a 42,000 year freeze, it basically opens us up to interstellar space travel and expansion, even without FTL speeds. The benefits to humanity are far too great to pass them up for the selfish needs of a single individual, even if she cannot comprehend her important contribution to science.
