"if there are political figures who have non consensual nude imagery"
"if there are political figures who have non consensual nude imagery created of them and then that gets into the hands of the Chinese government.”
As if the PRC state doesn't have access to massive supercomputing resources that could use CGI to generate a photorealistic animation of an obese Trump replete with large wobbling boobs and obvious deficiencies the bedroom department.
Fundamentally it is a question of repect, or rather the lack of respect involved in generating any imagery that embarrasses or demeans an individual. It doesn't neccessary involve nudity. Generating an image of person draped in NAZI regalia is an extreme example.
The rightness or wrongness of the generation of such imagery does hinge on the question of how much respect is due to the individual and whether that person is a public figure or not.
Stenciling a swastika on to the arm of Musk's infamous salute almost comes within the bounds of acceptable but not quite (IMHO.) In just about any other case totally unacceptable.
Can you legislate respect ? Of course not. Can you effectively ban this nonsense ? Of course not. Should you at least try ? I don't know.
As a postscript I would observe that the single greatest affliction in the US is the epidemic loss of respect for anything and anybody – a disease of a society that is invariably as lethal as ebola.
Unfortunately this malady also afflicts other nations but thankfully not to the same degree… yet.
