An interesting topic / thread. However, I don't see any comparison between this artist and the gender terrorist Julien Blanc, etc. To me (and I say this as a feminist) the furniture sculptures are deliberately provocative and, if anything, expose and ridicule male pornographic expectations and the stereotyping of women as both sexual and domestic objects.
I also see Allen's work as a critical intervention in the long artistic tradition of representing the female body. His work calls attention to those processes of representation that previous painters and sculptors have availed themselves of, and which are almost invariably fetishistic and voyeuristic (right from the classical and renaissance periods to the nineteenth century) but which are, perhaps, more insidious because those processes and intentions are glossed over. This is more-or-less the same kind of argument about ideology and the female nude which John Berger later made in "Ways of Seeing". And while earlier sculptors introduced qualities of tactility into their work to make the female form alluring, there is something cold and anti-tactile about these works (the materials used, in particular) that is actually very confronting. I have yet to meet any man who has viewed these works who did not find them unsettling. So, no, I don't think many people will be using this kind of work as a means of accessing or legitimating porn. I also think that art should sometimes confront and provoke us and point to issues of representation and history - I found it very disappointing that the exhibition / performance at the Barbican about slavery mentioned above was shut down by a vocal minority. The only problem about that exhibition, as far as I'm concerned, is that the kind of people who would have gone to see it would probably not have been the ones who most need to confront and learn about that aspect of Western history. Perhaps the same is true of this exhibition at the RA.
Also, I don't think it's necessarily true that Allen Jones is lauded, OP - his work has been controversial, and still is. There was an article about him recently by Zoe Williams (I think) in the Guardian which argued that his work was sexist. The problem is that every representation of the female body faces accusations of sexism, unless it is made by a woman. In fact, if you look at feminist art (which also dates from the 1960s) a lot of it looks very similar to Jones's work, ie. it is just as provocative and uses similar shock tactics in relation to the female body.
