Doxxing might well be used as evidence of a conspiracy to commit sedition, but by distributing the information widely it's strategically superior to holding it in isolation. It's easy to act with impunity against a lone individual, but if some unknown number of people are possession of the same information the marginal benefit of arrest is vastly reduced.
“Your approach is to limit political autonomy to zero and offer an institutional solution that will probably not be available.”
That is a straw man argument, undeniably so. It in no way represents my position.
I agree with you distributing information widely is superior to holding it in isolation, and I agree with you about reducing the benefit of arrest. Nobody said anything about just one person holding all the dossiers.
There are many ways to accomplish this which are not doxxing if the goal is real accountability.
If compilation of a dossier is treated as evidence of a conspiracy to commit sedition, then surely doxxing would be too.
