While there are points of comparisons we can draw if you like, I don't think think a little wicker doll or existing sex dolls or anything else are so similar to a life-sized, self-moving, reactive fake person who speaks to you that we can just say if one is fine then so is the other, though I already think existing sex dolls are probably not that good for some of their owners (people who are already particular varieties of psychologically vulnerable but clearly not being helped by this).
For the record, I also think something similar about other slave simulacra, though this is surely worse because for many just doing daily simulated sexual abuse is literally the one and only point of having it, and for many of the rest there's someone more in line with traditional ideas of AI psychosis, of a fake partner who always agrees with you and if they don't then you change their settings so they do.
But if we can acknowledge that the flattery robots can hurt your mental health, surely we can acknowledge that robots designed to receive sexual abuse with the same regularity and psychological untethering (of being able to dictate their responses) while being behaviorally grounded in a physical, lifelike simulacra of a victim presents cause for concern.
I'm not talking about any crime, that should be overtly obvious, I am talking about psychological impact from being constantly conditioned via this elaborate simulated "relationship" that you get to enact with great frequency.
Edit: as I said before, it's just observably, blatantly true that things on the internet that have much less experiential reality or concrete, behavioral reinforcement than this can, at minimum, cause unwell people to be more unwell. This is just a worse version of it that it seems much more easily could produce, among other things, even more actual physical violence than the other things already do.
