Except that you're postulating that the person doing the infringing be the one out of reach, puzzle. That still leaves the copyright owner vulnerable to being sued by the infringor for 'stealing' an idea or story.
I do think you're stretching it. It's a stretch to assume that someone who isn't the author and seeks profit from their work (or legal entitlement to it) could manage that anonymously.
Profit requires moving money, and legal entitlement seems to require moving lawyers. I haven't heard of a technology enabling a person to move either without exposing themselves to retaliation in a thousand and one ways.
I know of effective technologies to protect movers of information from being targeted. Physical goods and projection of power are a lot harder to conceal.
Regardless, a good solution against what you suggest would be abolishing copyright law so they can't sue you, and telling people who use your work "please send donations for this work to my account only". I bet that people who'd prefer paying would like to pay the original author(s).
What's their protection via technology, pray tell?
A nice technology for those who want to publish for money should be digital signatures and timestamps. Before handing your work out of your control, have an independent timestamping service digitally sign it.
Perhaps combine this with digitally co-signing the timestamped copy with multiple trusted persons (or use a notary if you insist on official channels, ink, rubber and paper).
That should give you adequate proof if a consumer of your work doubts whom they should pay, or someone claims they own what you made, or you feel pressing need to demand compensation from a person unjustly profiting from your work.
Those who don't profit however, can and probably will keep using your work in countless violations of modern copyright law, since multiple aspects of copyright law simply contradict how the world functions.
