Even if, you leave the original in a pristine state, the fact that multiple copies are available and can be used (for good or nefarious purpose), dilutes or erodes the value of the original.

And this is true for both digital content or something as intangible as an identity.

So I am not really convinced by the simple argument that since the original still exists untouched, everything is fine. Yes, this is surely convenient and better for the original author/owner/creator, but not enough to say nothing harmful happened.
